Minecraft keeps crashing

[Afro_]

Hi, I'm having trouble staying on. After about 5 seconds I am taken back to the Launcher with the message that MC crashed blah blah blah and that I should contact server owners. HALP.

Please spend some time looking next time... Also, for future reference if you want help with an error it might help posting more detail.
