The answer is Tim.
(the other names are also improper nouns; tom = male cat or turkey, jack = a piece in a game of jacks, and bob = a dipping motion; only "tim" is not a real word)
Hmmm...thinking about your riddle. I feel kind of stupid, like the answer should be at the forefront of my mind, but it's not.
