Noah has always been a bit of a cheeky rascal, definitely the less serious of him and Blake. When they're not fighting, they really can make each other laugh. And when Noah is really amused, you'll know it from his laugh. Blake was being silly in the bath the other night and Noah voiced his appreciation.
It always reminds me of Janice, Chandler's girlfriend in Friends, but it doesn't annoy me of course. I hope you'll find it funny too.
