Gravity, The Universal Mood Killer, Part 2

(I’m a customer, and overhear an elderly gentleman and the hairdresser who is cutting his hair. The gentleman’s wife is present, too.)

Hairdresser: “Do you want me to take off any more on the top of your head?”

Customer: “Yes, yes, go ahead!”

Hairdresser: “All right, but if I cut it any shorter, the hair up there will be standing on end.”

Customer’s wife: “Well, at least something will still be standing erect, then.”
