Credits and sushi

Two unrelated things?

Bright Eyes really likes the rolling credits on the ends of films and TV shows. He always has to watch right to the end.

I've been noticing that my bamboo mat for rolling sushi keeps getting taken out of the kitchen drawer, and I've been wondering what the attraction is.

Yesterday I found that he is using the bamboo mat as a kind of 'rolling credits' of his own. He hums music, unrolls the mat and pretends that the strips of bamboo are the words going up or down the screen.

I have no idea what to make of it!
