In light of the rubbish London episode earlier...
Choices? I'd say it's a choice between:
The one where they get a horse and call it Furious D
The one where they go to Florida and kill an alligator (starring Kid Rock!) and go on the run
The one where Marge gets mugged, starts working out, and becomes a female bodybuilder, pretty much raping Homer along the way
Though that recent one which moved Homer and Marge's university years to the 90s is really rubbish too...
