I saw this episode for the first time last night, and it has easily become one of my favourite episodes.
Debra and Amy share all kinds of secrets about their husbands, not knowing that they each tell their husband. When Ray and Robert find out, they are not pleased, so they turn the tables on their wives. Frank joins in the discussion, revealing some home truths about Marie.
This episode is one of the funniest Everybody Loves Raymond episodes. A secret is revealed by each character including:
*Ray crying out "choo choo" in his sleep
*Debra's loud belches
*Amy's inability to control her bladder when she laughs
*(and funniest of all) - Marie's admittance to using jars of sauce rather than homemade.
A brilliantly funny episode!
