This might go down as the funniest thing Abby has said ever.
We were in the hot tub together at my parent's condo. A lady in there with us, across from us, had big white hair. Not grey, completely white, and a big 'do'. Abby was staring for quite a few minutes. She smiled at the lady. Then she turned to me and quietly said "sheep". The woman didn't hear but it was all I could do to keep a straight face!
