This episode originally helped make the show more popular, due to a woman boycotting it. Basically, Peg gets depressed because her favorite bra is discontinued, and Steve knows where him and Al can buy it- at a lingerie store. They go just for the bra, and the store is really dirty.
An adult-oriented episode, and also a really good one. It seemed like it should've been TV-14, but it was a good episode that is an example of how much Al does in fact love Peg. My overall grade for this episode would be about a B+ or so, methinks
