I based this lesson on a short clip from an episode of The Simpsons (s22e05; from 03:58 to 06:18). The Simpsons' logo on slide 2 has a link to the episode on my flash, but the episode could easily be found, and then you could just edit the hyperlink.
The lesson is on using "used to" when speaking about something that happened regularly in the past or about how things were in the past. I haven't added a lesson plan, but if anybody needs me to, I'd be happy to post it. Also, I made the examples for the activity a little personal, but you can change it if you want.
Hope you find this useful.
