YES!!! It was SOOO hot in them!
The 'sets' ( time out in the park) were usually 30 minutes.
On hot hot days, when it hit 100 degrees...they would shorten the 'sets' by five minutes. If it got to 105, they would shorten the sets to 15 minutes. They would encourage us to 'stay in the shade, but it really didn't help that much. I would just try and be as energetic as I could, just to get my mind off of how HOT it was. It usually made the time go by pretty quick.
I won the "Character of the year" award three years in a row. LOL! I was mainly "Bugs Bunny" and "Yosemite Sam", and they sent me out to a lot of fun out of park specials. To places like the Warner Brothers lot, and I got to help present Fritz Freleng (Creator of many warner characters like Yosemite Sam) with his star on the Hollywood Walk of fame. So if you see pictures from that....with Fritz and characters behind him...one of those characters is ME!

wOW..That was way back in...1991 or 1992. A loooooooong time ago!
Being a 'character' is sooo much fun. I always hated seeing 'characters' just stand there and you could obviously tell that they were just bored or didn't want to be there. I hated that. So....I really played it up. Had lots of fun. I mean...if I HAD to be there..might as well enjoy myself, Right?!
One of the fun bits I made up, was a 'magic trick'. I would take a kids hat...point to it very dramatically. First in one hand then the other. take it behind my back, and then slowly pull one hand out(empty),,then the other hand out...(empty!).
The kids eyes would widen like saucers!! He'd look to his Mom and say "how'd you DO that!?!?"
I would then shrug, blow on my fist and rub it across my chest very proudly, then turn and do my best bugs bunny strut away- revealing that I had the kids hat....firmly placed on my tail.
The kid would scream 'HEEEEYYYYY!!' And the pace of my walk would quicken until he finally caught up to me.
All very fun and the crowds loved it.
As characters..the higher ups would encourage us to be lively..but not to really do much other than greet. I hated that. These characters HAVE characters! And being that I was studying animation..i wasn't about to NOT 'do' anything. LOL!
I attracted big crowds and got awards for it.So I guess they just let me do my own thing after awhile. Although they winced abit when I started to do splits, cartwheels, and backflips at the fireworks show.
But when you go off 'set' and take off those costumes...yeah. Your a big sweaty mess. LOL
Sorry for droning on!
