Some Cowboys are not very smart...
Back in about 1946, Roy Rogers, Dale Evans and Trigger came to our school to put on a "Dog and Pony" show.
Roy was telling the kids to study their Math assignments, because it was very important for their future.
He said that Trigger also did his math homework, and then asked Trigger to add 2 and 2.
Trigger obediently stroked the ground 4 times, whereupon Roy said: "C'mon, boy...one more!"
