My fave was the childbirth scene in the first season of Reba....when Cheyenne & Van tell Reba she can't go into the delivery room, so she's waiting out in the hall...then you hear Cheyenne yell, "I...want...my...MOTHER!"  

Then Reba goes, YES!  And runs into the delivery room.

i like the one on the nanny when niles and cc get married over top of fran, and in armywives when pamela has twins on the pool table during a storm!
