I really like these, thanks Kowalski. Hopefully be able to come up with my own variants.

Just been playing the alphabet thing with myself (haha that sounds slightly wrong!). It does work and instantly loads of cool/funny memories and experiences rose to the surface. All from a place of genuine interest/excitement on my part as well and not some 'high value' story I've pre-conceived.

The Manchester Improv nights look cool too. I may look into going to a London version. If any other London guys are interested, let me know.
