Here are some I have heard:
1) While towel boys were cleaning under the basket in a College BBall game
Analyst:..And the Ball Boys are getting busy under the basket
2) After Donald Driver made a catch in the Packers game
Analyst:...That was a great catch, especially with the cold balls on the field.
3) During a basketball game after some guy made a hookshot
Analyst: Wow! He really banged that hooker.
I am not kidding, these are all real.
