LET A FOOL HOLD HIS TONGUE AND HE WILL PASS FOR A SAGE

I bit my tongue this morning.

To "bite your tongue" has become an expression, used you might say something that would hurt or be offensive to someone, but instead remain quiet or murmur a courteous platitude instead.

But when you actually bite down on your tongue, the pain is... well, exquisite.

I can understand why - the tongue is a highly sensitive organ, holding many many nerve endings.

But God, why did you place it so close to my TEETH?!
