The funniest moment was when DS asked me what Viagra was because it was a sponsor for Mark Martin's car. I thought for a moment and said "A medicine for men," which seemed to be enough for him. (Thank goodness!)
That is so funny!
That reminds me of an incident when my DS8 was around 3. He was really into spelling words with his magnetic letters. Our friends and family members were so surprised to see the little one spelling words like "California", "Sleeptrain" and "Wal-mart". One day, we had some guests at our house. My DS spelled "Viagra" with his plastic letters right in front of them!
My very embarrassed DH was quick to explained to them that DS got the word from the TV commercial!
