Someone will ask, “Hey, why do you scratch the back your head so much?”

And the other will answer with their own question,  “Why does saliva always have to froth on the corners of your mouth?”

The other will say, “Dude, you froth too.”

The other will respond, “Now way, dude.”

“Yes you do,” the other insists, and will go so far as to present the evidence: a picture taken with a cell phone while the other one slept. And sure enough the froth is clearly visible in the close up shot.

“Oh well,” the other says, handing back the cell phone to the other. “I was sleeping.That doesn’t count. I don’t froth while I’m awake.”

“Your frothing now,” the other says.

“No I’m not.”

“Yes you are,” the other says and attempts to take another picture.

But now both of them are frothing at the mouth.

In the struggled to prevent or pursue a photograph, one of them dies.

Now the other is sorry to have mentioned the scratching at the back of the head.
