A few jokes of my own creation....
-What did the Tetris block say to his therapist?
"I just want to fit in!"
-Did you hear the one about the Dalek cook?
He wanted to egg-stir-marinate all humans!
(I think this next one still needs work)
-"Boss, I'm taking the day off. I have a touch of fever..."
"For the last time Johnson! Pac-Man fever doesn't count!"
I hope at least one of these got a smile out of you, we could do with a little cheer in these dire times...
