24 Simpsons characters in 2.5 minutes

Many people can do one or two impressions really well. In my field, though, it's important to be able to do many impressions in fast succession, moving from character to character.

Here's one of my favorite groupings: 24 Simpsons characters in two and a half minutes. @geke and I made the video below earlier this year at the beautiful Red Rocks Park outside Denver.
