VIDEO: Haren films Weaver dancing at J. Lo concert

Former big-league pitcher Dan Haren has quite the sense of humor, and since retiring, he's revealed some ugly baseball truths during Twitter rants while keeping his social media following amused with his near-daily jokes.

Haren continued his comedic antics Saturday when he caught Jered Weaver of the Los Angeles Angels dancing at a Jennifer Lopez concert in Las Vegas and posted the video on his Twitter account.

Weaver didn't look too happy about being caught, but Haren lived to tweet another piece of interesting information after posting the video, so he must be OK.
