Well, tall tales at least. The sort of outrageous nonsense that makes their eyes go wide, until the light of skepticism dawns and they call you on it. I get it from my Grandfather, the King of Turkey Tales.
He used to tell us, when we arrived at his house, "Oh, too bad you weren't here this morning! The chickadees were running down the road." I would instantly imagine a flock of small bird--a flock of Biblical proportions--running dowm the road in front of my grandparents' house on their tiny little legs. Yet, I also knew he was pulling my leg, and I loved catching him in it.
Tonight, I told a little girl whose bubblegum had burst all over her face that she shouldn't touch her chin, else her hand would get stuck forever. "I knew a girl who did that last year, and she's *still* got her her hand right there, all the time." She just grinned.
