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!"
A koala bear walks into a bar. He asks the bartender how he can get a little action for the night. The bartender points to a cute little trick at the end of the bar. So the koala bear walks up to her and in a few minutes they're heading to her place. When they get they're the koala bear immediately goes down on her. After a few minutes he jumps up and splits.
The next night, the woman spots the koala bear at the bar again and confronts him saying: "You owe me money!" "For what?" the koala asks. The woman rolls her eyes and tells him, "I'm a prostitute." The koala bear pulls out a dictionary and looks it up: "Prostitute: Has sex for money." The koala says, "I don't owe you a thing. I'm a koala bear. Look it up." Before she can protest the koala hands her the dictionary.
The woman looks up "koala bear" and reads, "Koala bear: Eats bush and leaves.”
