I’ve been going through Eugene Mirman withdrawal since FOX’s Bob’s Burgers, on which Mirman voices child keyboard prodigy Gene Belcher, has been on hiatus. Luckily, there’s Mirman’s Twitter feed (“If Romney just made an ad of himself in his bedroom singing ‘Sweet Child o’ Mine’ in his underwear, then voters would finally connect with him”) and the traveling all-star Eugene Mirman Comedy Festival. The Brooklyn fest was initially started as a joke, but with the help of his funny friends, it’s is now in its fifth successful year. Here’s how it’ll all go down: Tonight at the Croc, Mirman and Bobby Tisdale will co-host their wildly popular standup show “Invite Them Up.” Friday at the Neptune, he’ll postulate on UFO sightings and alien invasions with celebrity astrophysicist Neil deGrasse Tyson and acclaimed laugh-physicists Kristen Schaal and Paul F. Tompkins (this for a taping of the StarTalk Radio podcast). If your sides are still intact, the festival wraps up with two shows at both venues on Saturday (times are staggered, so you can hit both). The Croc features This American Life‘s Tacoma-born Elna Baker; and the Neptune lineup includes the raucous late-night veteran Bobcat Goldthwait. But as any fan knows from Mirman’s appearances at Bumbershoot, the roster always changes with drop-by guests. ERIN K. THOMPSON
