Down Hummingbird Lane

Old woman sitting alone at a table in a truckers's cafeteria...three tough, very road-weary drivers come in, see the only space to sit is at the table she's at.
They get their trays, sit down with her, and wanting to talk trucker stuff, decide to gross her out.
"Damn", says the first one, giving his armpits a delicate sniff..."I stink...haven't had a bath in three days..."
"Me neither," says his buddy..."In fact, it's been two weeks...."
"Hell, I haven't even been rained on in a month," says the third.
"I tried to change my drawers yesterday, but they fought me!"
The old woman smiles and says, "Would one of you smelly bastards please pass the salt?"
