Help indetify two movies

[WrestlingDeacon]

It's been awhile since I've posted here, but I'm trying to run these two movies down any which way I can and you guys have helped in the past. Thanks for any help this time.

 

 

I remember a horror movie from the mid to late eighties. The killer was a shadowy figure who used a stick with razor blades somehow imbedded in the stick to do away with his victims. I remember one scene where he's hacking away at some guy and we see the chopping of fingers. It's pretty gross. And the other scene is of a girl showering, she looks kind of like a very, and I mean very young Janeane Garofalo, except for being very well endowed. And then the killer comes in and, well, kills her.

 

This first one I remember seeing when I was very young so we're talking late 70s. It's about a man who is a teacher and turns into a kid at random times. He tries to keep it a secret. The episode I remember is when it's vaccination day at the school and the teacher turns into a kid and he gets vaccinated. Then at the end of the episode he becomes a man and the other teachers take him to get vaccinated again much to his chagrin.

Remember that flick where these guys come take a teacher and her students hostage, and they are in clown masks? I forget what it is called.

The first title--sounds like a job for Corey Lazarus.

 

I'll email a horror movie buff friend of mine on it, though.
