Fish Heads Lyrics
Fish heads, fish heads, rolly polly fish headsYumm!Fish heads, fish heads, eat them up
Fish heads, fish heads, eat them upYumm!Fish heads, fish heads, rolly polly fish heads
In the morning, laughing happy fish headsIn the evening, floating in the soup
Yumm!Fish heads, fish heads, eat them up
Fish heads, fish heads, rolly polly fish headsAsk a fish head anything you want toThey won't answer, they cant talk
Fish heads, fish heads, rolly polly fish headsYumm!Fish heads, fish heads, eat them up
I took a fish head out to see a movie,Didn't have to pay to get it inFish heads, fish heads, rolly polly fish heads
Yumm!They can't play baseball, they don't wear sweatersFish heads, fish heads, eat them upThey're not good dancers, they don't play drums
Fish heads, fish heads, rolly polly fish headsFish heads, fish heads, eat them upYumm!Rolly Polly fish heads are never seen drinking cappuccino in
YeeaahhItalian restaurants with Oriental women.
Fish heads, fish heads, rolly polly fish headsYumm!Fish heads, fish heads, eat them up
Fish heads, fish heads, rolly polly fish headsFish heads, fish heads, eat them upYumm!
Yum!Fish heads, fish heads, rolly polly fish heads
Fish heads, fish heads, eat them upYumm!
Fish heads, fish heads, rolly polly fish headsYummmm!
Fish heads, fish heads, eat them upYeeaahh

Bizzare song huh? He must have loved fish heads, or've been really bored. Funny, I don't really like fish heads...
WTF is "rolly polly"?
