This is changed significantly from how I first imagined it.
As originally imagined, Rich would react to Ellen saying card games are too complicated by thinking for a moment, then saying "I prefer Velma to Daphne" to himself. This would confuse Ellen and Larry, each of them failing to pick up on the context.
This would have been a reference to Scooby Doo, and intended to imply that Rich prefers smart, nerdy girls (no offense to Daphne, all Rich opinions belong to Rich, and do not necessarily reflect those of the author).
It wasn't entirely clear what exactly Rich meant by this even if one did get the reference, and it did rely on a reference, so I decided to do something else. I'll have other opportunities to reference Scooby Doo that are less likely to confuse anyone.
Something I also like better about this version is that it gives some insight into what Rich is actually looking for in women beyond the superficial. Granted, some of you might consider this too much information, but I like having it established anyway.
