You know those moments in comic books when someone's holding a tray of eggs or something very fragile and very breakable, and has a sudden and overwhelming urge to scratch his or her nose but can't afford to due to a possibility of dropping that tray of eggs?

Well, it happens to me. Under no other circumstances do I feel a need to scratch my nose (sometimes my ears). Only when I'm carrying a heavy box with breakable items inside, or like last week, when I was carrying a large dish of sliced potatoes, do I feel a certain itch and the subsequent urge to relieve that itch.

Oh, the irony of it all.
Gah!
