Who sings the song in "Knocked Up" that has the days of the week as the chorus and where can I get a copy?

umm is it police on my back by the clash???

"Well Im running police on my back

Ive been hiding police on my back

There was a shooting police on my back

And the victim well he wont come back

What have I done?

I been running monday tuesday wednesday

Thursday friday saturday sunday runnin

Monday tuesday wednesday thursday friday

Saturday sunday

Yes, Im running down the railway track

Could you help me? police on my back

They will catch me if I dare drop back

Wont you give me all the speed I lack"

i think those might be the right lyrics i got them off some site. i did see the movie and i remember that song being in it but idk if thats the one your thinking of lol

yeah, ash is right it's police on my back. It's on the clash's album Sandinista!
