Just invented an invisibility cloak. Everything you cover becomes invisible.
Unfortunately you can still see the cloak itself so further work is needed.
The wife and I were sitting on the couch watching the TV and it was boring so I thought I’d start a conversation.
Me: How many men have you had in total?
Wife: Are sure you want to know?
Me: Yeh, go on.
Wife: 7.
Me (after a pause): so I was number 7.
Wife: no, you were number 2.
