The plot thickened Monday on the set of Everybody Loves Raymond. While Patricia Heaton returned to work after calling in sick last week, her on-screen in-laws — Peter Boyle and Doris Roberts — were suspiciously MIA. Officially, their absence was health-related. Unofficially, there's talk they — like co-star Brad Garrett (who has refused to show up for work unless CBS shows him the money) — may be angling for a pay hike as well. All told, it's time Les Moonves set Plan B into motion and fired everyone. For the latest on Raymondgate, watch tonight's Extra, which, barring any massive, history-making blackouts, will feature another interview with yours truly.
