What’s the big deal? I had a teacher doing this daily back in the late 70’s! My Oceanography class.
Whoop’s! Not a chicken impersonator. Someone in the class would say “Quack quack” and he would get on the desk and quack like a duck! LOL
Bet I can top that - I had a history teacher in high school who would pick his nose and fling the boog boogs (that what I call them to my kids - lol) at the kids in the front rows. I always sat in the back. The kids would sit at their desks with their books open held up like shields. I kid you not!
