Here's the real reason you gotta watch out for wedding crashers on your big day: They will steal your money.

Some random 40-something dude just showed up to a SoCal wedding this Sunday, blended in (not sure how), hung out for 90 minutes (!), and then took off with the gift box which had around $60,000 worth of cash and checks inside.

He even tipped the bartender, according to the groom.
More from ABC News:
At a wedding held on Sunday, a suspect entered the wedding hall shortly after midnight, grabbed a gift box and fled through an exit, witnesses told Glendale Police.
Surveillance footage then shows the suspect fleeing the venue in a Mercedes SUV that appears to have been waiting for him.
The suspect is described by police as a male around 40 years old who is of White or Middle Eastern descent, who is bald and has a medium build.
The bride, Nadeen Farahat, says after the theft occured the whole wedding went silent, music and everything, and she sobbed on the dance floor surrounded by family members.

The suspect has yet to be identified.
