Will Yankee Joba Chamberlain be following new rules?

I didn't expect Joba Chamberlain to come back this season from his trampoline disaster in spring training. Heck, I wasn't sure if he would be be able to come back at all in his career. Yet there he was on August 1 in a Yankee game. Good for him. While he didn't pitch well yesterday -- he gave up four hits and two runs in 1 2/3 innings -- at least he was pitching in the big leagues again this season, and there is something to be said for that.

Now I hope Joba has learned his lesson and stops doing dopey things like jumping on a trampoline. Hint -- if he ever feels the need to say "watch this" when he's about to do something, there's a good chance it won't end well! Note to Joba -- here are some things you ought to stay away from doing as well:

• Archery
• Knife-throwing
• Surfing
• Hang gliding
• Beekeeping
• Zip lines
• Bumper cars
• Twister
• All form of jumping, including jumping to conclusions 

Stay safe, Joba!
