It makes sense. They've reaching the point where they have to go to college which always seems to be the harbinger of doom for a series.

:(

the show is still laugh out loud funny, which is rare these days.

You mean this is still on the air? hehe But seriously, it's a good show whose end has come.

Competely agree - this show consistently makes me laugh every week. I'll miss it. :( But I agree that it's better to end while the quality is still there rather than die a slow death.

Topher is an excellent actor who has had small parts in many films, including Ocean's 11 and Traffic. Kutcher - goofball, sometimes funny, but funniest as kelso, no question. The rest I haven't seen in anything else, except Kitty and Red (who has done voiceovers recently) - they'll do well also.

I remember the actress who plays Kelso's girlfriend in an Aerosmith video.
