Nevertheless, this will be reflected in her tip.

What did Penny mean, "you'd make a cute couple"?

I assume she meant the two of you...

...would constitute a couple that others might consider cute.

An alternate and less likely interpretation is that you could manufacture one.

As in, "Look, Leonard and Leslie made Mr. and Mrs. Goldfarb.

Aren't they adorable?"

If Penny didn't know that Leslie had turned me down...

...then that would mean that she, Penny, thought I should ask her, Leslie, out...

...indicating that Penny had no interest in me asking her out.

But because she did know I had asked Leslie out...

...and that she, Leslie, had turned me down...

...then she, Penny, could be offering consolation.

"That's too bad, you would have made a cute couple."

But while thinking, "Good, Leonard remains available."

You're a lucky man, Leonard.

How so?

You're talking to one of the three men in the West...

...capable of following that train of thought.

Well, what do you think?
