It's right up there with "but Dad, it's Smokey!" on the list of Lines We Repeat Needlessly, even in situations that barely relate. Kind-a like Steve, who has been know to utter "hey, watch where you point that thing" to no one in particular.
"It ain't gonna fit, Charlie." Cracks me up every time.
I also got Da Chimpz familiar with the line "Ba-gel for your Temp Tee?" Because that was another ad classic ... and something they've heard me mutter just about every time we pass the bagel bins at the Giant Beagle bakery.
