I have always had a very broad sense of humour and right from school, I would say I have been 'The Joker' in any group I've been in.
If I said that Keith Lemon had stolen my act I wouldn't be far off the mark.
I love 'practical jokes' and, I suppose 'teasing' strangers - in the nicest possible way - and I ALWAYS elicit laughter and smiles from them as they share in and appreciate the 'joke'.
Old ladies are my favourite because their reactions can be so unexpected and hilarious.
Just a few weeks ago I was with my wife and and some friends at a Garden Centre and I spotted a very well-dressed middle-aged woman having some difficulty getting what was her equally as well-dressed very elderly mother out of the passenger seat of her very expensive car. I went up to help her and as the old lady grasped my arm, she said; "Who are you?"

I said: "I'm the AGEING toyboy you ordered". I swear that she had a wicked glint in her eyes as she told me - in a very 'posh' accent; "An ASIAN toyboy? You should be helping me into the rear seats then and joining me".
Her daughter laughed, but not as loud as me, and as I helped her out of the car the old sweetheart thanked me and gave me a hug.
