My Dom story:
 
I was an extra in a brilliant film called "Baby Geniuses" and I was walking to the set when I hear a commotion behind me. Dom was rushing by with several paper grocery bags filled with food and a big log of bread sticking out.  He was with someone laughing and being everything you'd expect.  I held the door for them as they rushed by, apparently off to cook for the cast and he wasn't even in the scenes shot.

Aunt Kate: Where's Francis Jr.? 
Francis Abbot Sr.: I don't know, Kate. He told me he was coming up this afternoon. I thought sure he'd be here in time for dinner. 
Aunt Kate: One of my dresses is missing. Has he been at it again? 
Francis Abbot Sr.: No! 
[
stammering] 
Francis Abbot Sr.: Uh, n-n-no no I. 
Francis Abbot Sr.: [
explaining to Vickie] My son does this wonderful impression of Aunt Kate. He's got her voice down to a tee. And well, sometimes he likes to, uh, put on one of Aunt Kate's dresses to entertain at family gatherings. 
Vickie Pearle: I see. 
Francis Abbot Sr.: [
upbeat] Oh, you should have seen him last Christmas. Such fun. 
Aunt Kate: [
sarcastic] Yes. And when the police dragged him out of the ladies room at Sach's Fifth Avenue, *that* was fun.
