haha, ive heard this one before.
here's another one:
so a man is on an island. he finds a lamp and rubs it three times. out pops a genie and sure enough, says, "i will grant you three wishes." so the man thinks and says, "i wish i had a million puonds of gold." Poof! there's a million pounds of gold on the island. then he says, "i wish i had a nice new ferrari." Poof! ther's a nice new ferrari on the island. then he thinks long and hard and finally says, "i wish i was irresistible to girls." Poof! the man is turned into a barbie doll.
and another one:
so a lady is on a deserted island with her cat. She finds a lamp and rubs it. sure enough, a genie pops out. but this genie is really mean, and only grants the lady one wish. So the lady thinks and thinks and thinks some more, and finally says, "i wish my cat was arnold swchartzenneger(that is how you spell it, right?)." "so be it" says the genie. and poof! her cat is turned into arnold swchartzenneger. As the lady jumps into his lap, he says, "i bet you wish you hadnt had me neutered last week, huh?"
