My sister has been happily married for 25 years to a guy with one of
the quickest wits I have ever met. Here is just a sample:
He, a buddy of his and my sister are walking down the street one day
when they spot a dog lying in the sun licking himself in the usual
places. The buddy spots the dog and for no apparent reason blurts out
"man, I wish I could do that!" My BIL rejoions equally quickly "go
ahead, he won't mind."
Ever had a flash of inspiration afterwards where you wished you had
said it back then? One from my long gone Mother -
"Turn back, turn back, time in thy flight!
I thought of the line I needed last night ..."
