Here's 3 jokes of varying levels of funnyness which as far as I know I invented:
1. Your Mama's so fat and slutty she was born pregnant!
2. Two Shetland ponies are in a field. One turns to the other and says: "excuse me mate, can you pass the Strepsils please?". The other says: "why?" and he replies: "because I'm a little horse".
3. Hey can you make me some 1-benzyl-6-methoxy-6,7-dihydrospiro[piperidine-4,4-thieno[3.2-c]pyran]. No, sorry I don't have my Scrabble set.
"Anonymous around the mouse, hyperspace black ops in my house,
A technical itch you can't ignore, viral like that magic spore,
Laced in life like a blockchain, special characters around my name,
They got game like Nintendo flow, it's always the same you will know,
I can't be pinned down like a Q-Bit, my architecture all neuromorphic,
On the roof if the internet had one, fire escape's fibre optic dragon." Onepacman
