I have few talents in general, but my silliest talent is my ability to find small objects dropped on any floor, like finding a contact lens or earring back or anything on patterned carpeting (or any other surface) without the use of flashlights or special glasses. I think it's because I've done a lot of jigsaw puzzles throughout my life, but it could also/instead be because I do beadwork and am constantly dropping tiny seed beads and stuff on the floor/table.
I also do a great impression of Gilbert Godfried, and can do voices for all of the stuffed animals and dolls that my sister and I had as kids. Oh--and Deeanna Troi (sp?) from Star Trek.
One thing I do is pick up the accents of whomever I'm conversing with--after about a minute, I'm speaking in their accent (and I worry that I might offend someone someday). Russian, Indian, Spanish, French, British, Southern USA, East Coast USA (I was born there)... You name it, I speak your language within minutes of starting a conversation with you. I'm not sure if this is a talent/skill or a curse. Hahaha I revert back to my mostly-Midwestern accent (with a touch of East Coast) the second I'm speaking with someone else, however.
