I went into my local one night where this guy was bragging about being able to identify any wood just by the smell.
So we asked him to put his money where his mouth is and challenged him to a blind test.
First up - oak, yes quite right,
next - Ash, right again and so it went on for several more samples until we realised he was going to win.
Quick thinking by one of the lads, asks Bella the barmaid, whip your nickers off, which she did with her usual alacrity, he laid them on a bar stool and held it under the guys nose.
Argh! he says, you lot are being sneaky, but you wont win, that is a toilet seat made from an old kipper box.
