How many times have you woken up in the morning after a hard night of drinking and thought 'How did I get home?' As hard as you try, you cannot piece together your return journey from the bar to your home.
The answer to this puzzle is that you used a beer scooter.
The beer scooter is a mythical form of transport, owned and leased out to the drunk by Bacchus the Roman god of wine. Bacchus has branched out since the decrease in the worship of the Roman pantheon and bought a large batch of these magical devices.
