God I am so fricken old, and with no kids, I have no clue to most of the answers, although I knew all those little stories as a kid. So here goes, nothing;

1. Name the character who visited the Black Sheep.
   a. I can't remember but I think it was Robert Conrad and he flew airplanes of a really really big boat.

2. Name the character Simple Simon met on his way to the fair.
   a. Sorry I was not much into Simon and I hardly ever watched that silly music show. Especially after they picked some guy that could not sing worth a crap as a winner.

3. Name Mary's lamb that had fleece as white as snow.
   a. I think that was Lou, but I think he was bald, but he did have a pretty white head.

4. How high was the hill Jack and Jill went up.
   a. They started up a hill, but then it became a mountain, or so the chief guy from next Generation said, or was it the other way around, up a mountain and down a hill? I forget, like I said I am getting old.

5. Name the fair lady in the nursery rhyme, London Bridge is Falling Down.
   a. Only fair lady I remember from London Bridge era is Agent 99, man she was good looking, poor Max, he could never get a clue, to much time talking into his shoe.

6. How many times has the Little Star twinkled.
   a. Only once because all the scientist said that it was what started the big bang theory, another one of those stupid TV shows. You think we would-a learned.

7. How many sheep came back to Bo Peep.
   a. I don't think very many came back at all, especially when Gordon James Ramsey was here cooking up lamb chops and making mutton soup.

8. How many slices of bread did Tommy Tucker get.
   a. Only one, then his brother Carlson got mad when he took that slice with out asking and then slapped him silly and highlighted his theft on his main stream media news outlet ousting his own brother as a thief. The names were changed to protect the innocent, I mean the guilty.

I look forward to the real answers.

Okay, I was going to cheat and google but I decided that was cheating........

I am going to get these all wrong LOLL

1. The black sheep was the wolf? annnnddddddddd...........a guy in boots hid to shoot him? That is all I got.

2. Simple Simon met...... a rabbit called Tom who turned into a little Irish man that gave him a pot of gold?
   

3. Mary's lamb was named Lamb. It's a good old fashion name. Goes way back in the family. Tis true!

4. High enough that when he fell down he broke his head open....... I am 'Merican and don't use metric so that is the best I can do there.

5. Fair Lady or Fair for short.

6. 4 or Four

7. She lost them and hadn't a clue and neither do I so going with Zero.

8. None. Didn't he eat plums?

OKay. You made my head hurt so off I am to see everything I forgot from when I was 3 years old :D

This was fun. Thank you!

I was hoping for something simpler.. for example..

There once was a man from Nantucket..

I am still a little confused, but thanks for the brain game. !PIZZA I attempted but they were poor answers, apparently I am not familiar with this material at all. I will be diving into Nursery Rhymes next to try and make sense of it all. Now I am wondering how many times the stars twinkle and who the fairest lady was before Audrey Hepburn. Perhaps the sheep were named after imaginary cousins and she never told a soul that she had given them names and elaborate backstories while tending to her flock.
