At the beginning of the show Lester claims he spun a Gimmel (and claims that's the best roll), but lies, since the dreidel really shows a Hei. Which is especially ironic since Ana right afterward says "isn't Hey best?" If she's right, he could have won without lying. (Both Gimmel and Hei could be best, it depends on what version of the game is being played.)

Morgan: By the way, never trust a woman whose name is a palindrome.

Morgan: A relationship is built on trust, Chuck. Sex and trust. Am I right?
Chuck: Yeah, yeah, two big prerequisites I guess.

When Chuck picks up the dropped $100 bill, it is partially crumpled with an obvious crease in it. When he holds it up a moment later and flashes on it, it is nicely pressed as if it had never been crumpled or creased.

At 17.32min when Chuck gets out of the car, you can see a lolly sticking to his butt.
