I had a friend who loathed onions. Personally, I love them, but for him:

LET ONIONS BE

Come on friends, and let's all shun them
I speak of the slippery onion
May I see not even one then,
While we are together

Cho: Let onions be not in our food
Let all our food be onion-free
I hope you all will heed my plea
While we are together

Fa cannae no nasty ally-ally-ummy (X3)
While we are together

(Yeah, I know - it stinks.)
