According to
featherjean, the one thing I say the most often is "Where's my Blistex?" I maintain that this is not really my fault - you try combining perpetually chapped lips with a perpetually bad memory and see what your most common comment is!
Anyone else have a most common comment? For real fun, don't choose your own - if you've got someone around you that you spend a lot of time with, ask them what they think your most common comment is!
