Bill Cosby has a gun

Bill Cosby talks to Philadelphia schoolchildren in the infield while carrying a gun.

Yes, really.

Bill Cosby served as the master of ceremonies for the Philadelphia Elementary School shuttle relays in the infield. But before the races got underway, he spent a few minutes chatting with the kids and reporters.

With a gun in his hands.

Soon thereafter, Penn president Amy Gutmann took the gun from Cosby's hands and showed it off for all to see.

Then, she shot it. Multiple times.

Philadelphia School District CEO Arlene Ackerman also shot the gun multiple times. 

Okay, so it was the starter's gun for the infield races. But it was still amusing.
