Severe vomiting ensued

Many years later…

It is far more likely it has less to do with a dragon’s internal heat and more to do with how strong the acid in their stomach is, but the melting points relative to heat was the easiest point to make, heh. Dragons may possibly have a gastric acid composed of a hydrofluoric acid mix rather than the hydrochloric, potassium chloride and sodium chloride mix that is most common in most other living creatures. The outcome would be the same.
 
But yeah, I’ve seen a few stories and fics where a specific race or class were damn near impossible to get drunk (elves come the most readily to mind, makes for some wickedly fun DnD games at times, especially when playing a monk) and there’s usually at least one small section where they get to overload on blackmail material for their compatriots.

@NovaQuill  
I don’t know what effect heat has chemically on the innards of a creature with alot of it and all the other details we could extrapolate from the process, but what fun would it be to have a creature that can’t get drunk?
 
Except to embarrass anyone that can?

@Darth Sonic  
Considering digestion more or less consists of melting a product to get the nutrients out of it, and the lowest melting point of your standard stone is around 1200 degrees celsius, Sapphires around 2050 Celsius and achieving ‘liquid diamond’ at around 4726.85 °C. I’m gonna go with … not so much :D. A dragon’s digestive system would treat anything alcoholic like we treat water.

@NovaQuill  
One could justify dragons getting drunk by saying the dragons have different digestive tracts handling gems and normal stuff.

@Daneasaur  
That was my thought process behind it anyway. If Dragons can metabolize gems, I have a hard time believing anything could slow them down if ingested.

@Daneasaur  
Spike is immune to everything anyway, like all dragons. X3

And Spike, being a dragon, was immune to the contents of the punch because his system burned it up too fast.

For all we know Thorax just wanted to cuddle! ;3 coughcough

@Background Pony #D8FA  
I’m going to pull your endocrine system out of your body. XD

And so Celestia woke up with a bedbug.

Jesus, that’s creepy.

Looks like they aren’t responsible
