ideas for a broken ankle

Options
So a curb jumped out and attacked me while on a run and I broke my ankle. I've been off my feet for almost three weeks and am stuck on crutches for at least another two... And I'm going insane. I've started doing pushups and tricep dips as well as some ab work just to help kill the time. Any other ideas? I'm bored and getting insanely depressed sitting on a couch watching the Soap channel. I miss working out and I know I need to take it easy and take care of my body, but surely there things I can do that don't require me to be on my feet.

Any ideas? Thank you in advance.
