some slightly less sensible ones

FCC to Kentish Town, then Northern
FCC to London Bridge, then Jubilee
FCC to Elephant & Castle, then Bakerloo
SET to Stratford Intl, then Jubilee

for the really lazy people, just get on a NB Northern train to High Barnet and stay on it, it should then go back via CX to Waterloo.
