Looking for a song i doubt anyone can help me.

Basically my computer died and i lost all my music and i have a tune in my head of a song that i want but can't remember anything about it, beside i think it has the lyrics clowns, giraffe, trampoline or trapeze, circus, and hill. I think the song was about a love that was lost am pretty sure a fella sings it too.
Thanks.

Any ideas of the song lewis_cruickshank@hotmail.com feel free to tell me.

P.S i think the song might be from scrubs or house md but might be wrong.

Try "At the Zoo" by Simon And Garfunkel

The monkeys stand for honesty,
Giraffes are insincere,
And the elephants are kindly but
They're dumb.
Orangutans are skeptical
Of changes in their cages,
And the zookeeper is very fond of rum.

I think it's the Yardbirds cover of a song Called "Ha Ha Said The Clown
