I once worked in a hardware/lumber store and heard some funny questions asked at times, mostly by women....
Where is your caulk?
I need some caulk.
Where can I find a stud?
Guy asking new female cashier: Where are your nipples? (small pipe) Female cashier gets ticked off.
Old lady comes in, tells young female cashier up front she needs a screw, so female cashier walks her to back of store. Then female cashier standing behind lady says "Bill, this lady needs a screw. Can you help her?"
Lady says she needs a plug. I say "male or female?" She says "What's the difference?" Me (blushing): "Well I'll just show you." (I show her male and female plug.) Lady (now blushing too): "Oh I get it!"
Guy comes in and asks female cashier if she has a "6 inch hole saw". Guys standing around crack up laughing, cashier wonders why they are all laughing.
Others?
