Shut down jokes

I saw Stephen Hawking using an ATM. It is nice to see he had found someone before he shut down.

What noise does Stephen Hawking make when he dies? Windows shutting down theme tune.

Stephen Hawking's death was purely accidental. He clicked “shut-down” instead of “sleep”.

This one time I said to a person that they are dry, then I was wet (ba dum tiss).

My bully said I have to shut up. I said, "Shut down" (ba dum tiss).
