Why Barry Pasternack From Hot Rod Looks So Familiar

For most of Parnell's tenure on "SNL," Tina Fey was the head writer, and after his time on the show came to an end in 2006, she hooked him up with a recurring role on her "SNL"-inspired sitcom "30 Rock." He played Dr. Leo Spaceman, pronounced "Spuh-Che-Min," a lunatic general practitioner who was incompetent at every aspect of the medical profession. He couldn't inject anything into a comatose man's heart because "we have no way of knowing where the heart is. See, every human is different." That's just one of many classic Spaceman-isms, which can be seen in this YouTube compilation.

Parnell told Looper that Dr. Spaceman was loosely inspired by "SNL" creator and executive producer Lorne Michaels' personal doctor, who Parnell actually saw one time when he got sick during his first season on the show. "My experience was relatively normal with him," the actor said, adding that "he was kind of a showbiz doctor in a way. Definitely the seeds of Spaceman were there in him."
