Ah, I see. Groucho was great. He was probably one of the first major insult comics.
 
“I’d buy you a parachute, if I knew it wouldn’t open.”

Groucho stopped doing the German accent after world war I broke out.

@Aharon L’anglais  
I heard the reason Harpo’s character doesn’t speak is because a critic complained about his thick NY accent, and so Harpo did his next stage preformance completely silent, and found he got more laughs from that, so it stuck.
 
Also, Groucho’s character doesn’t seem German, he looks and sounds American, unless you mean “German-American.”

That was actually a red wig. Without their makeup Harpo and Chico were very difficult to tell apart. The red-headed wig came from sort of character Harpo played early in their career while they were performing on stage. Each of the four oldest brothers, Chico, Harpo, Groucho, and the much lesser known Gummo, each played their characters had some sort of ethnic or national stereotype. Groucho played a stereotypical German immigrant which was the closest to their real heritage. Chico played the stereotypical Italian immigrant, and Harpo originally played a stereotypical Irish immigrant, until a theater owner Welshed on them and Harpo told him that he hoped his theater would burn down, only for it to do just that overnight. Ever since then Harpo never spoke while in character.

“The secret to life is honesty and fair dealing. If you can fake that, you’ve got it made.”

Groucho : “There is only one way to find out if a man is honest; ask him! If he says yes then you know he’s crooked.”

“He’s had a change of heart!”
 
“That won’t help him, he’s still got the same face.”

“When I eat dinner with a woman, I expect her to look at my face. That’s the price she has to pay.”

“‘Strange dame?’ Sir, this lady is my wife; you should be ashamed!”
 
“If this lady is your wife, you should be ashamed.”

“And then, right before he died, I kissed him.”
 
“So it was murder, eh?”

@Swashbucklist  
“I held him in my arms.”
 
“I see, no wonder he died!”

@Swashbucklist  
“Ah, marriage! I can just imagine you bending over a hot stove. Only… I can’t see the stove.”
 
“Marriage is a sacred institution. Though, who wants to live in an institution?”

@Beau Skunky  
“Margaret, I have a confession to make. I really am a horse doctor. But marry me, and I’ll never look at another horse!”

@Ardashir  
Groucho: “I’d give you a parachute if I knew it wouldn’t open.”

@Beau Skunky  
Groucho: “Now go out there and fight for this woman’s honor, which is more than she’s ever done.”

@Swashbucklist  
Groucho : “Hey! Do you want to be a public nuisance?!”
 
Chico : “Sure, how much does the job pay?”
 
Groucho : “I have half a mind to join a club, and beat you over the head with it.”

@Ardashir  
The Marx Brothers were the best. Are the best.
 
“Not that I care, but where is your husband?”
 
“Why, he’s dead.”
 
“I’ll bet he’s just using that as an excuse.”

@Beau Skunky  
I mostly like Bud and Lou for doing what may well be one of the top five Universal horror movies: Abbott & Costello Meet Frankenstein.
 
“Tonight… when the full moon rises… I will become a wolf!”
 
“You and 20 million other guys.”

@Ardashir  
3 Stooges were great too. Not to into A&C, but they weren’t bad either. When I was little I also liked Laurel & Hardy.
 
I like old retro stuff. lol (Especially old video games.)

@Beau Skunky  
The Marx Brothers were and are great, but I’ve always been more of a Three Stooges/Abbott & Costello fan myself. Maybe because for some reason the Marx Brothers can get, I don’t know, a bit much after an hour and a half? They were just a little too crazy.
 
But they had some of the best one-liners in the history of comedy.
 
“Two beers, bartender.”
 
“I’ll take-a two beers too.”
 
“You can’t fool me. There ain’t no Sanity Claus.”

@DeadPegasus  
Kids these days don’t know the Marx Brothers, and such. I guess they wouldn’t appeal to people into stuff like “Family Guy,” or the latest Seth Rogan comedies.
 
Looking back, they actually were kinda edgy for their day. Groucho got away with some pretty quick risqué remarks, and with some insult comedy.

And no one else got that reference.
 
Damn us.

Harpo did have red hair. He & Lucy later redid the “Duck Soup” mirror gag.

I thought it looked like Nepolian dynamite
