1.   I had the family-planning abilities of a mad hatter.

2.   Carroll based his character of the mad hatter on a Mr Theophilus Carter, who was known in the area for his eccentric ideas.

3.   The mad hatter, the March hare and the dormouse.

4.   So both the March hare and the mad hatter are very mad.

5.   The conversations which are held between the March hare and the mad hatter are complete nonsense.
