Sometimes what happens in Vegas actually does stay in Vegas -- at least for two decades. Funny girl Janeane Garofalo is claiming she's been married for 20 years, and didn't even know it!

The Reality Bites actress told the New York Post that she and Big Bang Theory producer Rob Cohen decided to wed at a Las Vegas drive-thru chapel but never thought it would stick. "Rob and I got married, for real, which we had to have a notary dissolve not 30 minutes before we got here tonight," Garofalo said at the New York Comedy Festival reunion for The Ben Stiller Show. "We were married for 20 years until this evening."

Garofalo, 48, further explained, "We got married drunk in Vegas. ... We dated for a year, and we got married at a drive-through chapel in a cab. [We thought], 'You have to go down to the courthouse and sign papers and stuff.' So, who knew? We were married, and apparently now that [Rob] is getting married for real, his lawyer dug up something."

Cohen, 63, joked, "I'm gonna get all of that Reality Bites money!"
