Those aren't "reality" shows; they're sheer fantasy.
A "real" reality show would feature four mothers who have gone off on a week-long spa experience. In the meantime, the four fathers have to take their place. Each father has to get three kids up for school and get them up again and get them up again. Then he has to feed them breakfast and pack their lunches, taking into consideration their individual allergies and food dislikes. He has forgotten that none of them like mustard on their sandwiches and has to start over again. He has to referee sibling fights and assure the five-year-old that she was not adopted from the zoo, regardless of what her brother says. He must find and iron a clean white shirt that the 12-year-old didn't tell him the night before that he had to wear for a band concert today. He has to dig around in the couch looking for coins because someone didn't tell him she needed $10 for a field trip this morning and he hadn't had time to get to the bank last night. He has to convince the teenage daughter that she is not going to wear that outfit to school, all the while being told that he is the worst parent in the world.
Five minutes late because he has had to clean up after the dog puked on the new chair, he has all three kids in the car. Unfortuantely, the five-year-old has shut the door on her hand and the boo-boo ceremony must be performed to its conclusion. The kids are dropped off at three different schools and he now heads to his 9:00 meeting across town. Unfortunately, he has to stop at CVS first and buy a new pair of pantyhose and put them on in the parking lot. He puts his makeup on at stop lights and, all things considered, doesn't look like a clown.
Only ten minutes late, he stumbles into his meeting only to find out it has been cancelled, luckily for him because he receives a call from his hysterical 16-year-old daughter because she has left her report at home and IT.MUST.BE.TURNED.IN.THIS.MORNING. He goes home, picks up the report, cleans up another mess of dog barf, drops the dog off at the vet for a checkup and delivers the report to his daughter who is not waiting out in front of the school as promised. He has to honk the horn until she comes out, whereupon she informs him that he has humiliated her beyond belief and she will never forgive him.
At three, he picks up the kids, drops the 12-year-old off for hockey practice, the 16-year-old off at the mall and the 5-year-old off for a play date. Then he picks up a pizza, drops it off at the house and picks up the kids and the dog. Upon reaching home, he is informed by all three that that kind of pizza is yucky and they'd rather go to McDonalds. The five-year-old cries herself to sleep because she's missing her mother, he suspects the 12-year-old is looking at porn on the computer and the 16-year-old still isn't talking to him. There's still three loads of laundry to do and the dog has puked again. Nobody has done their homework yet.
At the end of the week, the father who has imbibed the least amount of beer and hasn't started snorting cocaine wins. If they've all four started on cocaine, the one who can kick the habit first wins.
