Reminds me of this old chestnut: What happens when dawn breaks? Yellow fingers.
"Dawn" is/was a toilet paper brand way back then.
OH and this classy one:
John Wayne Toilet Paper
An Indian walks into a trading post and asks for toilet paper. The clerk asks if he would like no name, Charmin, or White Cloud. "White Cloud sounds like good Indian toilet paper," says the Indian. "How much is it?"
"$1.00 a roll," the clerk replies.
"That seems pretty expensive," responds the Indian. "What about the others?"
"Charmin is $2.00 a roll and no name is 50 cents a roll."
The Indian doesn't have much money so he opts for the no name.
Within a few hours he is back at the trading post. "I have a name for the no name toilet paper," he announces to the clerk. "We shall call it John Wayne."
"Why?" asks the confused clerk.
"Cause it's rough and it's tough and it don't take no crap off an Indian."
