Their favorite joke is to offer Johnny his choice between a nickel and a dime Little Johnny always takes the nickel. One day, after Johnny takes the nickel, a neighbor takes 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's bigger?" Johnny grins and says, "Well, if I took the dime, they'd stop doing it, and so far I've made $20!"

A blonde, a brunette and a redhead are all stuck on a deserted island together. The island is 20 miles from the nearest inhabited island so they all decide to try to swim there.

The blonde gets 19 miles away from the deserted island, decides she's too tired to go any farther, and swims all the way back to the deserted island.
