Indeed, the infamous episode of Designing Women wherein the flatchested brunette with glasses considers getting breast implants and in the decision-making process wears "falsies", Jean Smart's character pairs up with the brunette and they both go out to a bar.
At the bar, two sharply dressed young men eye and approach the two busty women (one real and the other with falsies in), when the brunette confronts them and says, "Why did you walk over here? Why were you first attracted to us?"
Obviously making the point that the guys liked and were initially attracted to the two girls impressive racks.
In the end of the ep, SHOCKER! the brunette doesn't get the implants.
Barnacle "but anyway... Jean Smart is sexy and busty" Bill
