I can't resist me a good word-mangling program: http://emalmi.kapsi.fi/battlebot/#/line3 Odd lines are mine, even lines are battlebot rhyme:

    I like to eat chips
    It's my right to insist
    when you're in the area
    I make 'em vegetarian
    fried delicious in my mouth
    so girl give it to me right now

    teach y'all to crunch 'em down
    look who the fuck fed now
    I've got the cash to keep them flowin'
    My fan base spread and the shit kept growin'
    no french fries comin' near my crib
    gotta say yo this is weird rhymin'

Takes a bit of tweaking and flexibility on what you feed it, but it's surprisingly practical....
