Distractibility

So there's a problem at the church we've been visiting back home. Actually, it's my problem, but it's a tough one.

Twice now we've randomly sat a few pews behind a man and his wife. I couldn't tell you what he looks like, but I'd recognize the back of his head a mile away. You see, he has a bald spot exactly the shape of a pair of lungs- complete with the curve on the left side into which the heart fits nicely.

I cannot concentrate on anything else. I keep thinking about how the thinning hairs near the trachea would be like cilia. Help.
