Hi, is this some corny physics joke that all teachers pull on the first day of class?

My physics teacher was like "Oh guys, one more thing before you leave class. I want you to bring in a bowling ball, but I don't want you to buy it".

So, corny joke or should I take him literally? :B
Please and Thank You!

He may want to demonstrate some principle of physics, but only wants you to bring a ball if you have one. Don't bring one if you don't already own one.

Bring him a bullet in the face instead.

Honestly? I think he means if you have a bowling ball bring it in. otherwise don't.

bring him a melon and see what he does.

Either he wants you to steal one or it is just a joke
