"I was beginning to think Robin really was imagining him naked and then Ted comes in!"

I did think about going that way, but in the end I thought it was funnier to bring Ted in and have Robin start pretending too. And then:

"And very nice insert that Barney cooks naked."

I thought of the "punch line" and decided I absolutely had to go that way.
