Eastenders. Skip to 17:06. During a conversation, Michael asks Janine why she's jiggling up and down. Janine tells him that she needs the toilet but doesn't want to leave Scarlett (her baby), before telling Michael to wait with Scarlett while she runs into the toilet. Then she runs into the cafe toilet, only to find Shirley has locked herself in on purpose. She eventually persuades her to come out of the toilet, saying she is about to wet herself during that.
