Life's Little Mysteries

[Elspode]

Time to start the ultimate stupid resource thread. This is the place to put your questions. You know the type...the ones that should be obvious, yet are inscrutable and frustrating. We'll post our questions here, and hope for answers, serious or otherwise.

Here's mine to kick things off:

On the way to work this morning, I saw the happiest dog in the world. It was a boxer, sitting in his master's lap, in the driver's seat, flying down the the highway with his head hanging out the window, ears flying in the breeze and a trail of saliva spewing out in the wake. This dog looked as if he could go for 10,000 miles that way. I swear, he was smiling.

So, can anyone tell me...why do dogs like to go down the road at 70 mph with their heads hanging out the window, yet hate it so much when you blow in their faces?
