How does she know these things?

Katy always surprises us.  On our road trip this weekend she saw a Geiko billboard and said look "We can save you money with Geiko".  And just a few minutes ago she held up a Kudos bar and said "Is this 100 calories?", and sure enough that's what it said on the front.  We don't let the kids watch much TV mostly just videos so I have to guess that she knows this from the commercials.  It's encouraging and frightening all in one how much she picks up.  I guess they now market toddlers with all the slogans.
