If you’re looking for some laughs, head down to Hilarities downtown for Big Jay Oakerson. The New York City comic is known for being abrasive and not for the easily offended. So if you’ve got a thick skin, go check him out tonight at 8. Or see a performance called Appropriate, a new drama concerning a family who make disturbing discovery among their deceased father’s possessions. It starts tonight at 7:30 over at the Dobama theater.
