Quote from Ross in The One with Ross's Tan
Ross: Well, how bad is it? Tanning Salon Guy: Not that bad yet. But it keeps getting darker for the next four hours. Ross: So how dark is it going to get? Tanning Salon Guy: You got sprayed with two twos and- Ross: I'm a four? Tanning Salon Guy: Yeah, but your back's a zero. You're gonna wanna even that out. Ross: Really?! Tanning Salon Guy: You might wanna get back in there. Ross: Oh, okay!
