Could be. Some kind of arithmetic problem or something like that. 

Maybe theres already a wallet that requires a password to open.  Then just make the password complicated enough that you cant pull it off if you are drunk.

I need a drunk mode on my Lightning wallets. As lightning payments are easy to use, it’s easy to miss payments, so we’re going to need a new method of detecting payments to detect and reject invalid payments.
I will also need to implement a system to determine how drunk you are.
Yes. I’m drunk right now.
