Benjamin has always had a good sense of humor and "gets" most humorous situations. Jim taught him a funny joke about tomatoes that he's pretty much mastered. I'll let him tell you - it's much funnier in person.
So a few weeks ago, we're riding in the car and Benjamin says, "It smells like up dog in here." I wasn't really paying much attention to what he said, but I replied, "What's up dog?" and we laughed for a long time. He told me his 3rd grade teacher taught him that! Love it!
I recently played a song by Bare Naked Ladies for him called "Pinch Me". Towards the end of the song, the lyrics are "I could hide out under there / I just made you say "underwear"." He didn't really laugh too much when I played this song for him. However, this morning on the way to Nana's house, we were talking and he said, "What's that under there?" And of course, I said, "Under Where?" and we both laughed. I'm still giggling
