Do these count as Cheech and Chong movies?

I'm on a mission to watch every Cheech and Chong film and was wondering if these were considered part of the series.

It Came From Hollywood

Yellowbeard

After Hours

Thanks for your help. By the way, I'm also gonna listen to every Cheech and Chong album.

It Came From Hollywood has good Cheech and Chng moments and they are on it alot. Worth a watch or buy!
