Well, my nik borders on serial stalker! While playing Sega console game with a buddy of mine, he typed in 'jak' since it would only take 3 letters. I liked the name so much that most times that is how I sign off. But then later, I became a HUGE Bruce Willis fan. While watching 'Moon Lighting' one night, I thought, 'Here is a guy who is not the best looking guy in the world (kinda average), doesn't sing great (but very well), and has attitude. He's confident. I like that.' Since that time, I bought my first pair of Wayfarers, drank my first Seagram's Golden Wine Cooler, learned to play the harmonica, pierced my ears, cut my hair into a Ducktail, then I shaved my head (I was loosing my hair anyway), etc. I saw him in the movie 'Jackal' with Richard Gere, and changed to the lettering to match my previous nik. So, there you go.
By the way, for those of you who didn't know, Bruce Willis put out two albums on Motown Records, 'The Return of Bruno', and 'If It Don't Kill You, It Only Makes You Stronger'. The last one was the better of the two. Also, I think he was the first white guy to ever record on Motown.
