A Mathematical Proof that "Girls are Evil"
1. “Girls require time and money”;
girls = time × money
2. “Time is money”:
time = money
3. So girls are money squared:
girls = money2
4. ”Money is the root of all evil”:
5. So, girls are evil:
The above proof is incorrect because "Money is not the root of all evil". It is "The love of money that is the root of all evil" and of course "girls are not evil" (Proof by Majority Rule).
Prove that 2 = 1
If a = b (so I say) [a = b]
And we multiply both sides by a
Then we'll see that a2 [a2 = ab]
When with ab compared
Are the same. Remove b2. OK? [a2− b2 = ab − b2]

(Just in case you're wondering - the above proof is incorrect because in step 5, we divided by (a - b) which is 0 since a = b)
The above proof is incorrect because 100 cents = 102 cents ≠(10 cents)2
A Proof that 0 = 1
The above proof is incorrect because when we take the square root we must be careful to include both the positive and negative roots. There should then be two possible answers (one of which is to be rejected).
