“Why do they say we are a few sandwiches short of a picnic?”

“Because we’re insane, stupid.”

“Don’t call me that. You know I don’t like it. What I was going to say was, isn’t it strange that we can be a few sandwiches short of a picnic as well as being a basket case?”

“Why’s that strange?”

“OK, strange is perhaps not the right word. Inefficient.”

“Eh?”

“Yes, the expression should be: to be a few sandwiches short of a picnic basket. That way you can have one saying instead of the two.”

“Language is not like mathematics.”

“Why not?”

“It just isn’t. For example, mathematics is logical, language isn’t.”

“You mean, so people can say illogical things, and that’s not a problem?”

“No.”

“So why are we in here then, and they not?”

“Oh, just shut up. All these questions are driving me crazy.”
