Hilarious bettas

I've been working on getting my betta to do "tricks". So far he will eat & swim into my hand, jump out of the water to get food, and chase my fingertip across the tank. Recently he discovered the sinking pellets I use to feed the remaining members of the tank and will now dive to the bottom to go after it, then float back up when he sees my fingertip and the cue for his real food. Do you own bettas do silly things like this?

I have one that will jump out and tag my finger almost every time. That's his trick for a treat.

My sorority tank is awesome to feed. Sometimes they do dolphin jumps back and forth just before the food comes. With 6 of them it's a good show.

My office betta likes to flare at bald guys, I don't know why, and it's not something I trained him to do, just darned funny because one of my supervisors is bald and my betta always flares at his shiny forehead!
