But... why are they calling you?

Having lunch with a friend when his cell phone started vibrating in his pants pocket.
He tried to ignore it until it was obvious we all could hear it.
Instead of taking it out of his pocket to answer it, he fumbled through the material of his jeans trying to find the button to turn it off.
After several unsuccessful seconds, he finally gave up and reached into his pocket.
"Oh, no wonder," he sighed. "That's my Altoids."
