The one that really winds me up is:
"Think bike,...because I do, and immediately think of the kids' TV programme Byker Grove, in which TV's Ant and Dec play TV and music's PJ and Duncan.
This thought makes me immediately forget about not driving like a dick, and put my car into a hedge out of sheer disgust, whilst singing "Byker Grove! Ooooh Byker Groooove!"
I doubt this is the outcome they were expecting when thinking up this clever little slogan.
Well played, the Highways Agency. Bloody well played.
