Watch Joe Flacco and Colin Kaepernick dance in Beyonce's 'Single Ladies'

Jim and John Harbaugh divided their childhood bedroom with a line down the middle. It's a fitting symbol for a Super Bowl party, when attendees tend to fall into one of two categories: Those interested in the football and those interested in Beyonce.

During its endless pregame show, NFL Network attempted to bridge the gap between those two groups with a clip of Beyonce's Single Ladies video with the heads of the Super Bowl quarterbacks and Steve Mariucci. It's amusing, but to watch the reaction of NFLN's analysts, you'd think they had just been watching a clip of Eddie Murphy circa 1983.

CBS usually wins the competition for fakest laughter, but NFLN made a run in this clip. We rank the fakers:

5. Kurt Warner -- He doesn't.

4. Deion Sanders -- Primetime appears to be laughing. Or maybe it's a sigh of relief that they didn't play a clip of him rapping "Must Be The Money."

3. Steve Mariucci -- Simply happy his head got the prime Beyonce placement.

2. Rich Eisen -- Flashing a broad smile instead of forcing laughter is the mark of a true professional.

1. Warren Sapp -- It's the "I still can't believe I got into the Hall of Fame before Charles Haley" face.
