Mine, of course, stemmed from an episode of "Home Improvement" where construction worker Jimbo gave Tim Allen his own hard-hat, with "Timbo" written on it. Add that to a store we saw in North Augusta, South Carolina that was a constant subject in my bizarre little cartoons--"Jimbo's Gas & Goodies". AND the sinister cigar-smoking clown Zbo from "Are You Afraid Of The Dark?"--all led to me calling my sisters "Kbo" and "Cbo"...the first letter of the first name, followed by a "bo". They reciprocated and started calling me "Mbo". This was oh, 6 years ago. It's prounouced "Em-bo". It's funny, some folks think it's my initials! Sorry, those would be MER.--Mattbo
