I've told this story many a time, and many don't believe it.
A few years ago I took a friend to meet my dear batlady Grams. Grams made a snarky comment, to which I responded in kind, and she then flipped me the bird, much to my friends amazement. I know that I am not the only person on Earth with a grandmother who is at times a bit crude, but there are many people who just can't visualize "dear old grannie" swearing at the afghan she is crocheting. So here is photographic evidence that my Grams will indeed flip you the bird if you irritate her:
And for extra measure a picture of my cousin Ryan flipping her off about 30 seconds after walking in the door:
And a cute poodle picture to make up for vulgarity of this post:
