How about local celebrities, do they count? If so:
Since I'm in the northeast Ohio area:
John Lanigan, radio personality. When going into broadcasting, he was super nice and helped out by giving some much welcomed advice and also used a bunch of jokes I wrote for him on the air.
The "Real" Bob James. Another radio personality. Another very nice guy. Worked at an amusement park where he was making an appearance and was ditched there by my ride home. So I started walking home [14.5 miles!] and he saw me walking and was kind enough to give me a ride home even though it was out of his way. Told him I was going into radio and he also gave me some pointers. Talked to him on and off over the years till he left the area.
Gib Shanley. Local sports anchor, passed away a while ago. Made national news by burning an Irainian flag on TV during the hostage crisis. Never met, but have heard from more than one person that he was the biggest A-hole around and treated people like dirt. Friends mother worked at a restaurant, he came in and they served him, he complained about the food and then proceeded to dump it all on the floor and poured his coffee over it for good measure. My friend's mom had to clean it up and if looks could kill, he would have been a pile of ashes. He was thrown out and told by the owner to never come back. He then proceeded to pull the old "don't you know who I am?" routine and the owner told him "I don't care if you're God; you set foot in here again I'll have you arrested!"
Ted Henry. Recently retired news anchor from WEWS. Really nice guy, down to earth.
There are others and if I can remember them I'll post them.
