Here is a set of premises from the master of confusion and silliness, Lewis Carroll.  The object here is to come up with the ultimate conclusion to the three premises set forth.

1. No Acrobatic feats, that are announced in the bill of Circus, are ever attempted there.
2. No acrabatic feat is possible, if it involves turning in a quadruple somersault.
3. No impossible acrobatic feat is ever announced in a circus bill.

Don’t forget to post your answers, and have fun!

Umm…

How ‘bout:

Quadruple somersaults may be attempted unannounced, though they are considered impossible to do.

I’m sure I’m confused.

EDIT:
I think your premise #1 is missing a crucial NOT.
In which case, I should think the conclusion is quite different from what I have given above.

Well, the last word in the first premise ‘there’- where?  The circus?  The bill of circus?

If we say that ‘there’ means the circus- Basically whatever is not announced is what will be attempted, impossible or not.
