I am watching the Numb3rs episode whose last lines are:

Judd Hirsch (Alan Epps in the series), in response to a comment from Don about him “being right” (about trying to protect his dad from the danger of the terrorists, the theme of the episode), then Don says:

Thanks, …and for that, we’re grateful (speaking on behalf of the FBI), then, “alright? I mean, I’m grateful.”

Alan says, “Grateful?”

Don: “Yeah.”

And then Alan utters the immortal lines:

“Grateful? Grateful’s good enough, Don; I can sleep on grateful.”

Then, (Charlie talking to Don): “When did this happen? This whole new attitude?”

Don’s reply (which I wrote about in a previous post): “the new attitude is gratitude.”

It still is!
