Hmm, being about 8 years old and wondering if I could "tipple-tail" downstairs.
I could.
I just couldnt stop.
waking up after swinging on a rope swing in our local woods with my mates looking down at me and telling me I have a hole in through my lip.
Putting a plug into the socket without the back on (just to see if I had wired it up correctly) - that was fun.
It's a wonder I'm still here really.
