Aviva Drescher's wacky dad was a force for amusement early in The Real Housewives of New York Season 5, but his return is a bit more dramatic in Episode 17: "Don't Make Room For Daddy" (airing September 24).

Now that Aviva and Ramona Singer have gone from friends to enemies in the wake of St. Barts, things get majorly awkward when daddy dearest shows up to Ramona's charity event. Seriously. So awkward.

Get a sneak peek of the drama below.
