Very recently, on a train from Spain to France, I let off possibly the most evilest fart in the entire world, I was appalled with myself but prayed that it wouldn't spread.
However, a few seconds later I heard a kiwi voice behind me going 'oh my god....oh jesus....who is that....oh man.'
Several others joined in.
I hid behind my book.
In my view it takes real courage to own up to a fart and, since I valued my life, there was no way I was going to own up to this!!
