One of these things is not like the other....

The other day I watched "The Triplets" as Julie and I jokingly call them (her twin boys and Claire are 2 weeks apart in age). I thought I would be funny and switch Judd and Claire's clothes. I thought it was hilarious. But it didn't even fool Luke and Lily. Luke said, "Why is Claire wearing his clothes?" I tried to tell Luke that it wasn't Claire but he wasn't fooled and neither was Julie when she came to get them!
