I can say pretty much any word given to me backwards, super fast. Totally pointless but I'm great at it.
Wow! That's pretty cool. Have you ever read The Poisonwood Bible by Barabara Kingsolver? There's one character in that book - (Adda possibly) who thinks and speaks that way.
Oh, I'm thinking . . .nope, no, wait, I have a few hidden talents. I can juggle three medium sized lemons at the grocery store (source of entertainment for kids when they are little, more embarrassing when mom does it now)
I can tie flies, In fact, served my 4H club proudly. Demonstration day was a serious competition for us and most of the kids in our club chose to demonstrate a horse related skill (properly clean your tack, braid a forelock). I figured I might as well give them something other than the same. Made it all the way to the Eastern States Exposition where they gave me a booth and a blue ribbon. I had to tie flies for two days at a fair, but it was fun!
I can also quote movies (other than Jaws),
recite the Jabberwocky and Marc Antony's Speech. . Yes, that's all.
