Bob Saget unwittingly staged a part-real, part-virtual “Full House” reunion over this past weekend when he was in San Francisco for a show. The comedian stopped by the house used for exterior shots on his former sitcom, taking the above picture and writing, “In San Fran. Couldn’t resist.”

“Full House” co-star John Stamos responded, “Cool, the Munsters house.”

And co-star Dave Coulier chimed in with, “Can you see if my underpants are still hanging on the gutter?”

Hahaha, ew.

The “Full House” cast is no stranger to reunions. They all got together (minus the Olsen twins) in September 2012 to celebrate the 25th anniversary of the show’s premiere and it looked like they all had a blast with each other.
