Very true - MAN'S best friend. The following is an email that I received earlier today:
Give this a try.
A dog is truly a man's best friend.
If you don't believe it, just try this experiment.
Put your dog and your wife in the trunk of your car for an hour.
When you open the trunk, which one is really happy to see you?
Hm...surely there is a better way to prove that than by torturing both.
I worry about you :)
