I've heard all the usual shouts, but once and only once, I managed a reply. A souped-up Ka with four lads was overtaking me and one of them shouted, "Excuse me, are you gay?", followed by the usual laughs from the car. In a moment of clarity, I shouted, "For you baby, I will be". He turned bright red and his mates exploded with laughter, beeped and were off.
