I did it on the circle line once. Woke up at Hammersmith. Luckily though I was going to Paddington, so it wasn't the worst trip back. Epping, on the other hand...
Epping sounds like the kind of town people don't even live in on purpose. They just missed their stop and was so embarrassed that they moved there rather than admit their mistake.
Breaks up more families than war and infidelity combined!
