Do you think I can become a Yankee Phanatic mascot there?

Yankees don't do gimmicks

Are you out of your mind?

No Mascots for Yankees!! Just forbidden like facial hair or ponytails and things that Nature are unacceptable in the Yankees clubhouse

Unlikely

The Staten Island Yankees had SCOOTER, but they no longer exist.

Yankees used to have a mascot "Dandy"

I think Yankee Phanatic should be the Yankees offical mascot.

I don't think so. Yankees probably would be too uptight to have a fun mascot such as the Philly mascot is.
