Paradoxes. True mindtwisters

I got really interested in paradoxes and I want to know more. Please post your paradoxes

[i]Wikipedia: A paradox is a seemingly true statement or group of statements that lead to a contradiction or a situation which seems to defy logic or intuition[/i]

Curry's paradox: "If this sentence is not true, then Santa Claus exists."

I find paradoxes dumb because they're there for no reason. They can't be proved and only sound cool.

Step 1: Receive large sum of money anonymously.
Step 2: Invest in time travel with half the money, invest in stocks using other half.
Step 3: Invested money doubles in value. Send invested money back in time to yourself.

So what happens when you skip the second half of step 3?
