Wait, I have nothing lighthearted to say. OK, I'll make something up...
Have you ever had the experience where you either say, hear or read the same word a bunch of times right after another and suddenly it either sounds or looks really funny and out of place; like it can't possibly really be a word. That happened to me with "but" the other day.
Then again I can't even say the word "titmouse" without giggling like a schoolgirl.
P.S. MRhé: don't even think about posting a snide comment or I'll cut your jacobs off.
