Food for thought!

Well well, how bout a bit of gym-work for your brains? Consider the following:

Premise 1: A dry crust of bread is better than nothing

Premise 2: Nothing is better than a big, juicy steak.

P1+P2 = Conclusion 3: Therefore, a dry crust of bread is better than a big, juicy steak.

Besides the obviousness that it's wrong based simply on common sense and intuition, can you explain LOGICALLY why it doesn't work?
