how about...

boys are cheats and liars they're such a big disgrace,
they will tell you anything to get to second
BASE-ball, baseball he thinks he's gonna score,
if you let him go all the then you are a
WHORE- tocolrist studies flowers, geologist studies rocks,
all guys really want is a place to put their
COCK-roaches, beetles, butterflies and bugs,
nothing makes him happier than a giant pair of
JUG-glers and acrobats, and a dancing bear name chuck,
all guys really want to do is "forget it no such luck!"
