Howard said he was listening to Bubba the Love Sponge's show yesterday, and got caught up in a conversation Bubba was having about penis size. Howard reported how Bubba was leading a discussion about how much penises grow from flaccid to erect, which made him consider his own situation. Howard then mentioned he was "half-an-inch" flaccid, but got to six inches when excited, while Artie said he went from two inches to about five inches.
Howard proceeded to note that Bubba was also talking about how he and his fiancé were in couples therapy even though they weren't yet married, and he felt that it was healthy for any relationship. Howard then discussed how he and Beth could seek therapy about, for example, their feelings on having children, because he didn't want anymore since he already has three, but Beth may have interest in having a baby of her own. After Robin pointed out there was a chance one of Howard's condoms could break one day and thus produce another child, Howard acknowledged that was the worst scenario he could imagine.
This prompted Artie to pick up Howard's megaphone and do impressions of Beth and "Grandma Stern" as pay back for all the Dana and Grandma Caprio impersonations Howard has done the past few weeks. Once Artie was finished, Howard admitted he didn't like hearing his impressions, and promised to cut out his own impersonations of the people in Artie's life.
