Proof that Logic Can Be Fun:
Premise 1. If you consider the sub-proof SP, you'll see that logic can be fun:
Premise 2. You consider SP:
Sub-premise 1. All valid arguments which have a false conclusion have at least one false premise.
Sub-premise 2. This argument has a false conclusion.
Sub-premise 3. So, if this argument is valid, it has a false premise.
Sub-premise 4. But this is a valid argument.
Sub-Conclusion. Hence, this argument has at least one false premise.
(Lemma 1: You're probably thinking: WTF?! Just what kind of argument is SP supposed to be?!)
Conclusion: See? Logic can be fun!
