please help me find the name and artist to this song. one of my friends gave it to me and i don't know what it's called or who sings it. It's kind of a weird song sung acappella by a bunch of men. It's semi humorous and it's about liposuction. The opening lyrics are...

if all your fancy diet plans have got your head a' swimmin
and everything you eat must be approved by richard simmons
stop eatin' that birdseed friend
'cause what you really need is a procedure guarenteed not to impede your need to feed
liposuction
liposuction
the new immediate weight reduction plan
trade in the hand you've been dealt
and get surgically svelt
at your friendly neighborhood liposuction man

i probably mispelled or inserted some wrong words but PLEASE HELP ME
