Johnny Goodtimes will be hosting a science (and we use the term “science” very loosely here at JGT, Inc.) quizzo at the Fels Planetarium (222 N. 20th Street) on Saturday, April 22 as the Franklin Institute celebrates the final weekend of the enormously popular Body Worlds exhibit. Here’s the dilly, yo. To participate in what will be a quizzo event for the ages, all you gotta do is buy a ticket to anything going on at the museum that night. It does not have to be the Body Worlds exhibit. You can get IMAX tix or general museum tix if you want. Then join Johnny in the planetarium at 9 p.m. There will be plenty of stuff given away during the night’s contest. Free museum passes, gift shop gift certificates, and even Phillies tickets. There have been no rumors circulating about Johnny rapping at this event. Oh, and yes, there will be booze for sale at this event. Lushes.
