Corn on the cob

We're having corn on the cob tonight. I made up a song a while ago about corn on the cob, it goes:

Corn on the cob
Corn on the cob
Who likes corn on the cob?
WE DO!

I was singing it just now. Jack is very into rhymes lately. Guess what rhymes with corn? I'll give you a hint: It starts with a "P".
