The Tennessean jumps out on our posting of a confrontation between Reps. Stacey Campfield and Rob Briley on a bill which would allow fathers to get out of paying child support after paternity tests determined that their child wasn't theirs:

The clip is hardly unusual. YouTube has become a repository of memorable political moments, among them the video footage of Briley's own arrest for drunk driving last year.

His apology on the House floor was, in turn, also posted to the site.

Political fortunes increasingly rise and fall on such moments. During the 2006 U.S. Senate race, Harold Ford Jr.'s so-called "Memphis Meltdown" — a widely viewed parking lot confrontation with opponent Bob Corker — is considered to have been a factor in Ford's failed run.

And on the national stage, U.S. Sen. George Allen's comment derisively calling a rival's campaign worker "macaca" is seen as a turning point eventually leading to Allen's loss in Virginia.

There are plenty of congenial moments in Tennessee politics enshrined on YouTube, such as Rep. Curry Todd's comments on the House floor poking fun at Rep. Frank Buck's fashion sense, House Republican Leader Jason Mumpower's presentation of orange pants to House speaker Jimmy Naifeh, and Sen. John Wilder's retirement speech in the Senate.

The discussion of Campfield's bill, though, is notable for its testiness and personal nature.
