PGA Champ Jimmy Walker: Baba Booey Don't Bother Me!

It drives some golfers crazy ... but newly crowned PGA champ Jimmy Walker says the whole "Baba Booey" thing doesn't bother him one bit.

In case you're in the dark, Howard Stern fans have made it a point to shout "Baba Booey" after golfers rip their tee shots at major tournaments all over the world.

Earlier in the weekend, Graeme McDowell dropped an F-bomb after someone "booey'd" him at Baltusrol. He later apologized.

Some tournaments have threatened to boot fans who shout the catchphrase.

But Walker says he ain't worried -- and explains why.
