A hippie walks into a bar and grill. The waiter approaches and asks if he'd like to order.
"Yeah, a cheeseburger," says the hippie. "Not too well done, not too rare, but right in the groove."
The waiter brings the burger and asks about a drink.
"A cup of tea," he replies. "Not too hot, not too cold, but right in the groove."
The waiter, growing annoyed, brings the tea and slams it on the table.
Later, the waiter returns to ask about dessert.
"Yeah, some ice cream," says the hippie. "Not too much chocolate, not too much vanilla, but right in the groove."
Exasperated, the waiter retorts, "Why don't you kiss my ass. Not the right cheek, not the left cheek, but right in the groove!"
