Chevy Chase Moment . . . With Blood

My parents needed some help getting the Lionel trains to run in a circle around the tree, and so I volunteered to troubleshoot the track -- which involved crawling under some furniture, as the tree was placed in a tight space -- and this didn't turn out very festive, as I banged my head on the underside of a desk, on a very sharp point of wood; I relieved some of the pain by yelling "motherf*cker," and I felt badly about this for a moment because my parents had company over and my children were in earshot, but when I emerged from under the desk, I found that i was bleeding from an ugly gash on my head, and then I no longer felt guilty about the use pf profanity . . . it was warranted.
