You don't go to a funeral home expecting to see stand-up comedy, even if plenty of eulogies often include lighthearted anecdotes. But on the last Saturday of each month, the comedian Ben Wasserman invites you to a funeral home in Greenpoint to laugh about grief and mourning with ''Live After Death." In this one-hander, Wasserman explores how he found catharsis after losing his father, grandfather, uncle and several friends over the course of three years. Expect some crowd work and clowning, too, from a guy who was willing to _paint with his rear end on a livestream for MTV. Each month's show features an opening set from a stand-up who is straight-up funny, not funereal. Wasserman's guest for the Memorial Day weekend performance is Petey DeAbreu.
