Saw through? Penetrated? Decoded? Grasped the meaning of?

Does anybody recognize a quote that's something like "Congratulations, you really got to the bottom of that single entendre"?

The phrasing is probably wrong here but I can't check because I can't remember where it's from.

Passing through on network to say that you may be thinking of the Buffy line, 'that's great, you've really mastered the single entendre".
