After Kim guilts Greg into attending church and joining its Daddies Groups, he makes a pleasantly surprising discovery about what the group's really all about.
When they go to meet the minister, he tells them that the Redskins won in overtime. Since Jimmy and Christine mentioned a second service, it would seem to put the time at well before 12:00 noon, even as early as 10:00 or 10:30am. The earliest the game would have ended is 1:00pm PST -- after both services are done. [edit]
