                        It's Thursday, which means it's time to take care of the
                        bathrooms.


                        00:00:03.501 --> 00:00:05.781

                        Wipe those mirrors down, clean your toilet,


                        00:00:05.782 --> 00:00:08.341

                        bath sink, vacuum and mop the floor.

                        Stock up on toilet paper. Oh,


                        00:00:09.782 --> 00:00:12.781

                        I need to do that. Replace towels and rugs,


                        00:00:12.782 --> 00:00:15.021

                        empty the trash, clean mirrors,
