I’m all for a good prank and this is certainly an example of a good prank. It’s safe to say that just about everybody on Earth is somewhat afraid of sharks, especially Great White Sharks. So this lady going up to a “tank” and getting scared so bad that she falls down is no surprise. You almost feel bad laughing at her.
Just imagine watching Shark Week with this woman. She’d keep falling down, breaking everything, and screaming. You’d have to change the channel or ask her to leave, there’s no other option.
