Imagine, you're young, in love, in Vegas, Drunk, and ya decide it would be fun to do one of those 'drive-thru' weddings!

Great Idea right?

Fast-forward 20 years and you want to marry your long-time fiance' but out of the blue comes the news that... ya CAN'T because you're already married!

OOPS!

That's what happened to comedienne Janeane Garofalo and 'Big Bang Theory' producer Rob Cohen!

After that night they dated for awhile and the booze-distorted memory of that event was a fuzzy haze.  They broke up, moved on, and forgot about it.

"Rob and I got married, for real, which we had to have a notary dissolve not 30 minutes before we got here tonight. We were married for 20 years until this evening. [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."

DOH!
