Which has never, ever been produced on VHS OR DVD.
This has happened to me a few times: a movie I really loved is not brought out on video or DVD. But you can sometimes find an MTS3K-d version or something like that. I found the movie "Stranded in Space" (about an astronaut who lands up on a parallel Earth where there are three moons and everyone is left-handed) had been MST3K-d and watched it that way. Joel and the robots didn't even bother me I was so eager to watch it again!
... I'm still looking for "The Astronaut" with Monte Markham and "The Aliens Are Coming" (TV pilot from the '70s) if anyone knows anything...

To get back on topic...
We often get parents who are in denial about their children. Now, when a child cannot cope we have procedures to follow. The first time s/he doesn't do homework, warning. Second time, break detention. Third time, SMS to parent. Fourth time, phone call. Fifth time, meeting.
What happens is, usually the child hasn't done homework in ANY subject and so the parent has gotten about six SMSes. We track these via computer and know if the SMS was received; we print out all the SMSes on a monthly basis. Then we try calling. You'd be amazed at how many parents, when they see the school's number, do not answer. Or worse, they LIE on their forms about their numbers, and we've been sending SMSes to strangers! If we eventually get hold of the parent and manage to get the parent to the school, parent will usually promise the moon. "I will check Johnny's homework every day and make sure he does it!" And nothing changes.
Then, when we want to retain the child in the same grade at the end of the year, the parent develops amnesia. I had this conversation last term with a parent:
Me: I'm sorry to tell you this, but Johnny will be retained in Grade 6 next year.
Dad (Johnny's father): I don't agree with that.
Me: He's not coping, as stated in numerous SMSes to you.
Dad: When I came at the beginning of the year, you didn't tell me!
Me: It was the beginning of the year.
Dad: You could have phoned.
Me: I tried to phone on (list of dates).
Dad: My phone didn't ring. You must have used the wrong number.
Me: I also sent SMSes (gives list of SMS dates).
Dad: I never got those.
Me: Well, how about you give me your number now so I can check.
Dad: Gives number.
Me: (Checking) This is the number I called and sent SMSes to.
Dad: I didn't get those. You must have typed in the wrong number.
Me: We're getting off the point. Johnny isn't coping. He cannot go to Grade 7.
Dad: I don't agree with that.
Me: Frankly, Mr Doe, whether you sign the forms or not, we will be presenting all the evidence, including the SMS printout, to the education department, and they will make the decision.
Dad: I'm not signing then.
Me: All right.
And the education department? Took a cursory look at the forms, printouts, evidence, and signed off on Johnny remaining in Grade 6. I can't wait to see Dad's face at the end of the year. (Which I know is juvenile, but really.)
