It really is amazing what kids pick up on. When I worked in a daycare, we finished getting ready for parents early, so the kids were sitting on a bench waiting for parents (it was a rainy day or we would have been outside) So I encouraged them to sing some songs. They were preschoolers, mostly 2 and 3. We did a few like old mcdonald and then I asked for suggestions of what they wanted to sing. One little boy kept raising his hand. First he wanted "All my Ex's live in Texas" and then when I vetoed that he wanted "There's a tear in my beer" LOL. We told his mom and she was mortified and blamed his father, LOL. My husband is hard of hearing so we used closed captioning now. My teens were watching Monty Python and the Holy grail and sometimes I was shocked to realize what they were saying, I had never noticed before until it was printed on the screen.
