Class (computer programming) Puns

It was BASIC training.

I said I wanted to take more programming classes because I really liked the one I took last year.

My offspring tells me they can't take any computer classes.

Confused, I asked why.

"Because I'm non-binary"

True story, happened last night. I have never been so proud.

So, today was my CNC class. For those that don't know what CNC is, it's basically the computer programming, and execution of automated machining and manufacturing. To program it, there is a very long script you have to write to tell the machine what to do.

He was reviewing his own code in front of the whole class, when he realized something, he's missing an R-plane. He says "Where is my R-plane?" I respond, "Probably at the R-port"
