Back in the day, of the early days of Phineas and Ferb, I spent waaaaaay more time posing things out than is necessary (I blame my history of being an animator). However, this makes for a really fun drawing! It is from the episode “It’s About Time” which was a two parter. Kent Osborne and I co-wrote and co-boarded part two. He was my first writing partner on Phineas and Ferb and we had a LOT of fun working together!
Here is part of the episode: http://www.youtube.com/watch?v=PI55zvo42cA&feature=related
