A compilation of "Whose Line is it anyway?", a show about 4 comedians improvising the whole show based on what the host says, it's a really fun show (and it's for free online).
This sketch is named "Scenes from a hat" in which the host draws cards and it's suggestions from the crowd and they have to come up with as many ideas as possible.
Really funny and a good way to spend time. too bad the show ended.
