I think I bought a fake bag on ebay!

Drunkness is not an excuse for anything...you are still guilty of having knowingly bought a fake.
You could have been drunk when you put your Ebay bid in, but i guess you were sobbered up when you completed the transaction.

ehhh yes Dad.

you are still guilty of having knowingly bought a fake.

Guilty as charged Sir.

Few Glasses of wine on me, gonna pop into ebay, see if I can pick up some bargins.
