How did the bat boy do the blowing trick with his beanie?
About 1:30 in there is a montage of the Knights streaking to the pennant. There is a short bench shot with the bat boy doing a magic trick where he blows into his thumb and his beanie rises up.
It's an old gag, but... How is that done?
TIA,
Why? I came into this game for the action, the excitement... Listen, kid, we're all in it together.
