Zack: Well, Leonard, we were hoping you'd go in on Monday.
Leonard: Okay.
Marissa: And they say, for the best results, between now and then, you shouldn't have sex.
Zack: Sorry, bro, I know it seems impossible to go for five days without, but I believe in you.
Leonard: Five days? My record is 24 years.
Penny: Uh, I think that also means no flying solo.
Leonard: Oh. Then my record is 14 years.
