Oh, so that's where I got that habit from!
Just watching this on TV for the first time in years and realised something.
Everytime I go bowling and I think I'm about to get a strike, I turn my back to the pins and put my hand to my ear to listen to them fall.
I figured I got the idea to do that from somewhere. Watching this again I saw Bill Murray do the same thing. So I'm guessing that's where I got it from!
