Three blonde men are stranded on one side of a wide river, and don't know how to get across.
The first man prays to God to make him smart enough to figure out how to cross the river. So God turns him into a brown-haired man and he swims across.
The second man prays to God to make him even smarter. So God turns him into a dark-haired man and he builds a boat and rows across.
Then the third man prays to God to make him the smartest of all. So God turns him into a woman and she walks across the bridge.
Little Johnny is always being teased by the neighborhood toughs for being stupid. Their favorite joke is to offer Johnny his choice between a nickel and a dime. Little Johnny always takes the nickel, causing no amount of snickering and glee among the bullies.
One day, after Johnny takes the nickel, nice Mr. Johnson pulls him aside and says, "Johnny, those boys are making fun of you. Don't you know that a dime is worth more than a nickel, even though the nickel is bigger?"
Johnny grins and says, "Well, if I took the dime, they'd probably stop. Right now I'm up more than twenty bucks on those mooks!"
