In his early life as a stand-up comic, Steve Martin used to get laughs with inane props such as an "arrow-through-his-head." But, he also posed off-beat logical conumdrums, which his audience would laugh at, but perhaps not understand.
For example, in his magic world of Bananaland, he claimed that both of the following statements were true:
Reliving his memory of this routine, Steve Martin commented: " I loved implying that the one thing I believed in was a contradiction."
- All chairs are green.
- No chairs are green.
Why should Steve Martin's logic earn a grade of "Zero!" in that these two statements are not necessarily contradictory?
