Joey Gladstone in the hot seat!

"Full House" star Dave Coulier was grilled about his connection to "You Oughta Know," which even he admits his ex-girlfriend Alanis Morissette wrote about him back in the day, on last night's "Watch What Happens Live."

But Andy Cohen wanted to know some specifics -- asking Coulier about being bugged "in the middle of dinner" and certain x-rated movie theater shenanigans. 

Dave wasn't too forthcoming with the dirty details, but it was sure fun to see him squirm!

Thanks to Bob Saget and John Stamos for speaking up a bit too, revealing some pretty funny Alanis anecdotes from the couple's time together.

These guys have been on a roll this week, from their amazing, can't-miss appearance on "Late Night with Jimmy Fallon" to their new Super Bowl commercial for Oikos.
