I do love most of this 50 'most intellectual joke I know' list, honestly. And "change comes from within" is a fitting successor to the buddhist with the hotdog (I'd make it the same vendor just to drill it home). My favourite?
I'd tell you a UDP joke, but you probably wouldn't get it.
So meta, so dumb, so not worth explaining...intellectual is clearly not the word, although some of the jokes definitely qualify.
What's your favourite (on the list or not)? Let us judge you with appropriate Internet rigour.
