Who Was In Both How I Met Your Mother and 30 Rock?

Kristen Schaal was in both How I Met Your Mother and 30 Rock. Obviously this means that Hazel Wassername was so downtrodden after losing Marshall and Lilly as best friends (couple segment) in How I Met Your Mother S3E11 that she considered leaving New York and returning to rural Virginia where she was a bit of a celebrity, being the first person in over 70 years from her town selected to be on a Jury. She decided to give it one last chance in the Big Apple, so she took a job at NBC and decided to be best friends with Liz Lemon in 30 Rock S7E10, figuring that if she can be so funny all the time, Liz must be a really nice, open, and friendly person.
