Dexter told Delilah that he just discovered something really fun to watch. If you go in the bathroom and wait until someone has been sitting on the seat and they get up, quickly jump up and look inside the seat. He says it is so much fun to watch the water inside spinning in circles and disappearing like magic. After the water disappears, it comes back slowly from some hidden place and suddenly it is all back just as it started.
Delilah followed his advice and agreed that this magic seat is soooooo coooool! MEOW!
