Joke 5

So a dumb guy is on the phone ordering pizza:

"I will have a pizza 3/20 pepperoni, 8/20 plain cheese, 5/20 mushroom, 9/20 hawaian, and 11/20 vegetable"

The pizza man replies "But that adds up to more that 20!"

The dumb guy, offended, shouts "You know, there are 3 kinds of people in this world, thoes who can count, and those who cant!!"
