Just thought of this one. Two guys are sitting in a bar. One of them is getting close to receiving his doctorate, and he loves apples. So while the second guy is chugging a pitcher of beer, the other guy is snacking on a Granny Smith apple. ""Hey, I've been pretty sick recently, but I'm feeling better."" Apple Guy spoke up. ""Well, you know what they say, an apple a day keeps the doctor away!"" Beer Chugger quotes. Apple Guy never got his PhD....
