Signs

Signs is a "hippie" protest song made famous by Canadian rock band Five Man Electrical Band. Stan tries to sing this in the Season Nine episode, "Die Hippie, Die"

Background
Stan Marsh's political conviction changes him into becoming more like the "college hippies" that arrived in South Park for the Hippie Jam Fest concert. He starts dressing and playing an acoustic guitar to fight the "corporate fatcats" that control the world.

Trivia

 * The rock band Tesla had a hit record with their cover of this song on their 1990 album Five Man Acoustical Jam.

Lyrics
And the sign said "Long-haired freaky people need not apply" So I tucked my hair up under my hat and I went in to ask him why He said "You look like a fine upstanding young man, I think you'll do" So I took off my hat, I said "Imagine that. Huh! Me workin' for you!"

Sign, sign, everywhere a sign Blockin' out the scenery, breakin' my mind Do this, don't do that, can't you read the sign?

And the sign said anybody caught trespassin' would be shot on sight So I jumped on the fence and-a yelled at the house, "Hey! What gives you the right?" "To put up a fence to keep me out or to keep mother nature in" "If God was here he'd tell you to your face, Man, you're some kinda sinner"

Sign, sign, everywhere a sign Blockin' out the scenery, breakin' my mind Do this, don't do that, can't you read the sign?

Now, hey you, mister, can't you read? You've got to have a shirt and tie to get a seat You can't even watch, no you can't eat You ain't supposed to be here The sign said you got to have a membership card to get inside Ugh!

And the sign said, "Everybody welcome. Come in, kneel down and pray" But when they passed around the plate at the end of it all, I didn't have a penny to pay So I got me a pen and a paper and I made up my own little sign I said, "Thank you, Lord, for thinkin' 'bout me. I'm alive and doin' fine."

Sign, sign, everywhere a sign Blockin' out the scenery, breakin' my mind Do this, don't do that, can't you read the sign?

Sign, sign, everywhere a sign Sign Sign, sign
