A bit of naughty, sexist fun, just in time for the weekend and for absolutely no other reason than because I can. (And for reference purposes, I heard this one from my Pops last night!)
Question: Do you know why women wear panties?
Answer: Because US state law decrees that all manholes must be covered when not in use!
What can I say? It made me laugh when I heard it the first time for some or other reason ;)
