Lucky 13!

It’s Friday the 13th! Unless you are huddled inside, staying away from black cats, mirrors, and ladders, you should celebrate this least lucky of days with a marathon of “Friday the 13th” movies! Videology will screen the first four of the teen slasher flicks today as part of the Brooklyn Horror Film Festival, going on through Sunday.

4, 6:15, 8:30, and 11 pm at Videology [308 Bedford Ave. at S. First Street in Williamsburg, (718) 782–3468, www.videologybarandcinema.com]. $13 each.

Going green

Make up for your weekend indulgences with a healthy, early-morning jog along the waterfront! The Brooklyn Greenway Half-Marathon (and the much less-punishing 5K) will set off on a circular route to Greenpoint and back (or along Brooklyn Bridge Park and back). Then you can indulge again at the after-party, at the Hop Stop beer bar across the street from the race starting point.

Free jazz: Afro-Cuban jazz band the Pedrito Martinez Group will kick off of the Brick JazzFest with a free concert on Oct. 14.

Dem Bums

It has been 60 years since the Brooklyn Dodgers ditched their hometown for sunny Los Angeles, and some of us still aren’t over it. Get your feelings out at tonight’s discussion with author David Krell, as he reads from his book “Our Bums,” which deals with the team’s legacy, including the impact of hiring Jackie Robinson, the African-American to play Major League Baseball.

6:30 pm at Brooklyn Historical Society (128 Pierrepont St. between Henry and Clinton streets in Brooklyn Heights, www.brooklynhistory.org). $5.

Funny stuff

This is your occasional reminder that on any random weeknight, there is amazing stand-up comedy happening in Brooklyn. Tonight, the “Harriet” show welcomes Todd Barry, Wyatt Cenac, Josh Gondelman, and the bizarre ballet-like antics of the Cocoon Central Dance Team. Check it out!

8 pm at Littlefield (635 Sackett St. between Third and Fourth avenues in Gowanus, www.littlefieldnyc.com). $12 ($10 in advance).
