My bad spelling means at least 12 disappointed people.

OK, so I can't spell 'Impromptu'. In two posts I made the common mistake of spelling it 'impromtu' without the P.

But it's worked out pretty well, the mis-spelling seems common to google users and this site has had 15 hits this week from people searching for... "free impromtu mind reading tricks" or a similar variant. The mis-spelt version comes in at 10th position on google.com

I bet they were gutted when what they got for their effort was a dick gag.
