Dunno but it wouldn't be the first messed up sign I've seen!
Whenever you see something dodgy like this (whether its signs, or someone pulling a bad pint)... you just have to bring to mind... who would ever apply for such a job? Unless it was all they could get

As such it's just amusing now rather than angering, but I'd love to add to the collection.
The SHCOOL brings the infamous SOTP to mind!
(I am so smart! I am so smart! S--M--R--T! I mean S--M-A-R--T!)
As i'm already posting pics and i dont want to dredge up an old thread i may as well pop something in from the same roll - the dodgy extra-wide corsa on skinny tyres

Looks like a particularly badly made brand of new-wave iron or something dunnit..
the quality's duff because it was zoomed and clarified from this 6x4 photo (wasnt using my digital

):

but I hope the general cockeyedness of it comes through (and the max power sticker which is the mod that has come off best, out of bumpers, arches, lights and tints!). Just too bad you can't see all the bubbles in the tintwork and the assymetrical slant on the lights!
