Yesterday, I had one of those moments that you absolutely live for.
I was sitting at a stop light beside a car that had pulled slightly ahead of me. I look sideways out my window and notice a large dog directly across from me, sitting in the back seat of the car beside me. The dog (a Wheaton Terrier) was staring intently at me while the driver and his passenger were carrying on a conversation. I stare back at the dog for at least ten seconds, and then for some reason decided to feign a lunge at him. Then, the silent comedy unfolded.
The dog goes absolutely nuts, barking at me (although I can't hear it through the two sealed windows of our cars) and scaring the bejeezus out of the passenger. The passenger does a classic head-thrown-back-and-hands-shooting-up-in-the-air move, along with the silent (to me) scream.
It was all I could do to keep my enjoyment to a mere smile as the light turned green and I drove away.
Classic slapstick comedy. What a treat.
