Bob Stoops doesn't say hello in this commercial. He mouths it, and may have said it in person when they filmed this commercial during the second bye week of the Sooners' season, but be clear: that weirdass voice coming out of Stoops' mouth at the end is not his, and Bob Stoops will not just hand you a scholarship based on a Youtube clip. (Hugh Freeze, on the other hand, will give you three or four for a nice GIF of you scoring a touchdown. #wintheday)
We thought it was weird the first time we saw it, and the kung-fu dub gets weirder and weirder the more we watch it. Stranger than a solid minute of other random "hellos" and sound effects dubbed over it, you ask? Only one way to find out, and that's by experiment. Dr. Freek, please start said the simulator.
Results varied, except for the part where Bob Stoops says "BALLS OF STEEL" in the Duke Nukem voice. That part is gigglefart funny every time we watch it, and cannot vary across any number of studies no matter how many times you watch it.
