I found this site that claims that these are the 100 Funniest Words in the English Language.
I found these to be the most funny:
Argle-bargle – A loud row or quarrel.
Crapulence – Discomfort from eating or drinking too much
Kerfuffle – Nonsense, balderdash.
Crudivore – An eater of raw food.
I have to find a way to introduce these into daily speech 😛
