This is Pete and Dud at their finest, folks. I don't know how many times I've watched my Best of What's Left of Not Only...But Also tape and I still laugh out loud. The bit with the father and son ("Your Uncle Bertie is a dirty, dirty man") and the scene in the art gallery ("Have a sandwich; my feet are killing me") are classics. The dynamic between Peter Cook and Dudley Moore is fantastic and watching Pete drive Dud to giggles with what he says or by the way he stares at him (most notably in the art gallery and the reptile house) is just a riot. There's some pretty bizarre British humor here so it may be kind of an acquired taste for those of us here in the States, but if that's your thing, you can't miss Not Only...But Also. That sounded like a pitch, didn't it? :-)
