About 10 years ago playing golf and teeing off on the 18th with my, then, usual grace and agility. One of the guys commented that I didn't hit the ball so much as bludgeon it, in fact MacBludgeon it. This stuck and there were people at the golf club that only knew me by that name. Since shortened it to MacB as it's easier and fits better on a cycling jersey.
Real name is Alastair MacDonald, no I'm not being especially revealing. Prior to adopting MacB I used my real name on forums, as I use my real picture, so it wouldn't take Einstein to find it.
According to my Mum my christian name should have been spelled Alasdair but my Dad had been a bit drunk when registering the name and used a T instead of a D. According to my Dad he'd had to go along with my Mums 'poncy' selection but wouldn't wish the D on me, so had deliberately changed it to T.
