Apart from all the things like people coming up with a theory and then other people then coming up with that same theory or invention or whatever independently - I think this happened with both the phone and the theory of evolution - also weird shit happens to me like this:
Hadn't thought about my first girlfriend in years, had a dream about her, got up, left the house and met her.
Same deal with a mate from school I hadn't seen in years.
And today I was in the shower this morning thinking Joe Dolce's Shaddap You Face kept something off the number one spot but I can't remember what.
Then the first thing when I got into work some bloke says to his mate "what kept Uktravox's Buenna off the number one spot?" And I said "was it Shaddap you face?" And he was like "yeah it was!"
I expect two replies. Both sarcastic.
