Get into a taxi and yell, "Follow that car!" at the top of my voice
Take part in a Death Star style chase (I've had to settle for laserquest)
Do that skydiving indoor thingie
Dance on top of a table
Do a standup comedy course
Spend the night in a haunted castle
Stay overnight in a lighthouse
Stay in a Scottish castle overnight
On my last day at a job pretend all our phone lines have been cut off and I'm a robot (no real customers will be harmed in this call)
Write a Mills and Boon (that's kind of half way between silly and serious, if only I could crack the formula!!)
Write a crime novel (actually that one's serious)
And a few other serious ones like see the Northern Lights, visit New England in the Fall, go into the desert with the Bedouin, and see the Rockies. Though this has actually made me realise I've somehow managed to do lots of the things I wanted to so far in life, amazingly.
