Eating your own dogfood?

(OK, that’s not really the right title but)

Another from JMcAndrew:

Why is he scratching himself with his foot? Is the joke supposed to be that his wife is feeding him dog meat and he’s mimicking dog behavior?

I dunno either. But it does make me think of the classic joke:

I was at the grocery store checkout buying a large bag of dog biscuits and a woman behind me asked if I had a dog. I was feeling a bit crabby, so I told her no, I was starting The Dog Biscuit Diet again. I added that I probably shouldn’t, because although last time I lost 50 pounds, I ended up in the hospital in intensive care.

Her eyes about popped out of her head. I went on and on with the bogus diet story and she was totally buying it. I told her that it was an easy, inexpensive diet and that they’re nutritionally complete: the way it works is to load your pockets or purse with biscuits and simply eat one or two every time you feel hungry.

Finally she asked if something in the dog food had poisoned me and was that why I ended up in the hospital. I calmly said no…I was sitting in the street licking myself when a car hit me.
