After everyone finds out Monica is not pregnant, much of the wedding reception is spent figuring out who is. Phoebe pretends it’s her, to cover for Rachel, but Monica realizes the truth. Chandler surprises Monica by announcing he’s been taking dancing lessons; but his wedding shoes are so slippery, he can’t dance. Joey changes out of his film costume, but all he can find is a tennis outfit. Mrs. Bing’s date is a Broadway producer, and Joey goes way too far trying to impress him. Ross changes the seating arrangements to be nearer a pretty woman (Mona), but ends up at the kids table instead. Each attempt to dance with Mona is foiled by dance requests by the female children. To impress Mona with his sweetness, he lets them stand on his feet while dancing. Rachel takes another pregnancy test to be sure; it’s positive, but first Phoebe tells her it’s negative, so she has a chance to realize how she really feels. Joey has freakishly tiny feet.
