I was in town the other day, and came across a couple of old friends who were with a blonde.
The guys said "Hey, watch this John." One pulled out a nickel and a dime and held them out for the blonde to see.
He told the blonde "You can have one, but only one. Which one do you want?"
The blonde considered for a couple of seconds and then thoughtfully took the nickel.
"Oooohhh, it's bigger and shinier than the dime," she said. The two guys burst out laughing.
I felt bad for the blonde, so later on I pulled her aside and explained to her that the dime was worth more than the nickel, even though it was smaller.
She promptly replied, "How many times do you think they'll pull this trick if I take the dime? Like, duh."
