Whenever I am singing to myself, I replace the lyric, "heart" with "fart" such as "Owner of a lonely Fart", "I left my Fart in San francisco" or "Broken Farted". I can't help it.
At the end of every loaf of bread I save the crusts in the freezer because of some childhood thing about kids starving in a 3rd world nation and our freezer is packed with old bread bags each with a pair of frozen crusts.
I sniff at the end of sentences like Mr. Furly from Threes Company, (god I hate that - stop me please).
I'm a guy that spends time on his hair even though you can't tell the difference. (If only #52 in section 945 would STAY IN PLACE!)
I shave in the shower with no mirror which I don't think is strange at all but others seem to find it odd.
