Joke: Two eager athletes approach the football coach telling him they want to play on his football team. Okay says the coach, but first we have to give you a test to see if you're intelligent enough to play on my team (select your least favorite college team). They go to the classroom for the test. The first question on the test is " Old MacDonald had a ______." After a few minutes, one of the guys whispers to the other... "Hey... what did old MacDonald have?" The other guy exclaims, "You dummy! Old MacDonald had a FARM!!" "Ohh Yeah.... Okay." says the first guy. A couple of minutes later, the first guy whispers again... " Hey... how do you spell FARM?" "Oh c'mon you dummy. Don't you remember the song?
Punch line: "Old Mac Donald had a farm! E-I-E-I-O!!!"
