Barack Obama -- Roasts The Spurs ... It's Hard to Hate Old People

The Barack Obama comedy tour continued at the White House Monday ... when for the second time in a year, he roasted a pro sports team to their faces. This time, the NBA champions the San Antonio Spurs were in the crosshairs.

Among the targets ... THE ENTIRE TEAM ... with Obama explaining why it's hard to hate a team full of senior citizens.

He also took as few shots at Coach Gregg Popovich and joked about Matt Bonner's aspiring career as a food blogger named "The Red Mamba."

The Comedian-In-Chief did the same schtick last year when the Seattle Seahawks came to visit .

Remember, tip your waitress.
