when something happens that may or may not be funny and your immediate response to it unknowingly could be translatedliterally and make the scenario hilarious
while pedro was trying to pull out a dingleberry after taking a slam he yelled "piece of crap" as it was being pulled out and then busted out laughing realizing that a dingleberry was in fact a "piece of crap"...literally hilarious

Yours are the limbs, my sweeting.
You look divine as you advance,
Hillarious when retreating."
