He used it during last week’s Football Night in America highlights, and now Keith Olbermann dropped it again tonight: The “boom goes the dynamite!” quip.

It’s a curious revival for an on-air catchphrase that had a 15-minutes-of-fame tenure some four years ago. I, for one, liked the silly sound of this SportsCenter-esque soundbite when I first heard it, so I’m glad it’s been resurrected on network TV.

I wonder if the original phrase-coiner, one Brian Collins, is feeling ripped off. Olbermann did infuse his enunciation of the “boom” with his trademark dripping-irony, so I’m thinking any legal claims are null and void.
