The video this is from is from a crossover between the two Doctor whooves seriesoctor whooves and assistant(Doctor with Derpy as his companion) and Doctor Whooves adventures(Doctor with Twilight as his companion). In the episodes, the two groups crossover and switch Doctors and companions: Twilight's Doctor is more focused and rational while Derpy's doctor is more of a goofball and so he annoys her
I just love your Q and A sessions! You're boyfriend would make one Hell of a cannon voice for the Doctor, and as you for Derpy! Whenever I read a fic or a comic, you'rs are the only voices I hear... and I swear, I don't mean that in a crazy way!
Haha! I like how Derpy and the Doctor kinda switch places! Like, in the first one, Derpy's the one yapping her mouth of and the Doctor's the one staring at her weirdly (you know, with the nervous little sweat drop), and in the second one, the Doctor's the one yapping away and Twilight's the one rolling her eyes with the sweat drop XD
