I might have been a dick in a past life and purposely lock my friend or of their phone while drunk at the bar.
1. Wipe the phone and restore from backup via iTunes. 2. If you have find my phone you can remote wipe the phone. 3. If you have neither you can put it in DFU mode and wipe it.
All of these prevent access to your data which is why you have the lock out feature in the first place.
