Caleb was looking through my wallet last night and examining some of the bills. (I know, amazing I actually had some cash ;) )
I was in the kitchen doing dishes and looked over into the living room when I heard Caleb ask his daddy if he knew George Washington and Abraham Lincoln.
Charles just replied, "Well, I know of them but I never knew them." You had to be there to get the full effect but it sure was funny! ;)
