Hank is mean to Bobby

I was re-watching the Bluegrass episode, and it hit me how unnecessarily rude Hank was to Bobby the whole entire episode. It's only the very end that Hank defends Bobby when Kahn was talking bad about Bobby. I felt so bad for Bobby the whole episode. Especially when Bobby tried to join in on the band, and Hank yelled at him😭 Are there any other episodes where Hank was extremely rude to Bobby?

I do love me some Hank Hill though
