The flashbacks show Leo getting drunk in 1998. He must have been lying in "Take Out the Trash Day" when he said he hadn't had a drink since 1993.
Jordan says that Woodrow and Edith Wilson have been dead for eighty years, but Edith lived into the 1960s.
In a flashback, C.J. says that Bartlet has ten years on Hoynes. But in "Enemies", Hoynes says he is fifteen years younger than Bartlet. Presumably, C.J. was rounding off.
In the flashback scene where C.J. and Toby are tossing the basketball back and forth, when you look out the window behind Sam, it's snowing. In the window behind Toby, there is no snow.
Leo: My father was an alcoholic, his father was an alcoholic, so in my case...
Jordan: Ain't nothing but a family thing?
Leo: That's right.
Chairman Bruno: I would like our 10-minute breaks to be closer to 15 minutes than they are to a half-hour.
Jordan: I don't like this. You pay me $650 an hour, you tell me everything.
Leo: What do I have to pay to only tell you some things?
Jordan: I don't know, but you have to pay it to another lawyer.
Leo: I went to rehab, my friends embraced me when I got out. You relapse, it's not like that. "Get away from me." That's what it's like.
Bartlet (to Mrs. Landingham, in a flashback): Speaking of crusty New England relics.
Mrs. Landingham: Governor, does it frustrate you to constantly aim for humor and yet miss so dramatically?
Bartlet (on the phone to Leo, who is about to testify): Listen, I don't care that much about your ass but if you need to perjure yourself to protect me you're going to damn well do it.
Leo: Sir, this isn't a secure phone call. So I'd like to say to the 17 global intelligence networks listening just then, that he was kidding just then.
Mike Casper: There's no amount of money, manpower or knowledge that can equal the person you're looking for being stupid.

Josh: I'm gonna help you. 'Cause you know why?
Leo: 'Cause you walk around with so much guilt about everybody you love dying, that you're a compulsive fixer?
