As we all know,our man Dan is very nervous and bites his own toe nails.

The fact that he's getting older,means his feet are further away than ever.
His "technique" is to stand on one leg,on the coffee table, in firm belief that the higher he stands the nearer his feet become,and crunch his way around his toes!he quite obviously didn't see the Jello smears
on the coffee table surface!
