You’ve never heard of a grizzly BEER?
You don’t understand why he’s looking so puzzled. Then he says, with a mixture of amusement and bemusement: “You’re not trying to say grizzly BAIR, are you?”
It rhymes with AIR???
You wonder if he’s pulling your leg.
Are you sure it’s not grizzly BEER? You say EE-UR, and DEE-UR, and FEE-UR, so why not grizzly BEE-UR?
