Kobe Bryant was not a fan of Chris Kaman's nap during Cavs game

Rule one of being a Laker: Don't get on Kobe Bryant's bad side.

Role player Chris Kaman may be in trouble because Kobe didn't like his naptime.

The only player on the depleted Lakers' bench at one point during their win over the Cavs Wednesday, Kaman sprawled himself out and caught some Zzzs -- while the action was going on right in front of him on the court.

Kaman's nap has gone viral but Kobe isn't one of the people laughing.

In a piece written by ESPNLosAngeles.com's Dave McMenamin, Bryant said:

"The last week's been horrible. That Cleveland game, it was crazy. And then [Chris] Kaman goes to sleep on the bench, it's like when big brother is not around, you start doing crazy [stuff]. So, it's been rough. It's been rough."

Angering big brother is never a good sign, especially when he's a legend with five rings.

Bryant has been out since mid-December with a knee injury but still plans to play this season. If that comes to fruition, Kaman better brew some coffee or load up on Red Bull because sleeping on the job is not going to be a part of Kobe's agenda.
