Two professors were arguing over who has the dumbest child. Each professors thought his child was the biggest idiot. The first professor said "there's no way that your child is dumber, my son has to be the biggest idiot in the world". The second Prof said "no my son is the biggest idiot". The first professor says " let me proof it to you. Hey Jake (Jake runs to his father) I don't know if I left myself at the office or not. Would you run there and find out. If so then tell me to come home and eat dinner." The son says gleefully "sure dad" and runs off.
The second professor not wanting to be outdone says "oh yey! Watch this! Hey Sam come here (Sam runs to his father). Here are two pennies with one buy a microwave and the other a car." Sam says "ok" and leaves. The professors kept on arguing.
Jake and Sam meet in the street and they start arguing which one has the dumber father. Jake says "well listen my father told me to check if he is at the office or not. Well all he had to do was to call the office and find out himself. Two minutes and he would have been done himself. That is stupid if I've ever heard it". Sam says "well that is nothing. My dad told me to buy a car with one penny and a microwave with the other. But he didn't tell me which penny is for the car and which for the microwave".
