Defining State Abbreviations

Postal abbreviations for states--we all know them (well those M states can be tricky)--we learned them in elementary school right?? Well yesterday the Duggar family was on the Today show. Spencer and I were watching and I noticed that they were interviewing the family from Florida--FL. Then we had the following conversation:
S: I know what FL means.
M: What, Florida?
S: No, the F stands for family and L stands for lots.
I guess even a 5 year old can recognize a big family!!
