I’m looking for examples of this technique in television shows. It needn’t be American television, but it does need to be something made for television. Thus no cinema, no novels, and no short stories, unless you simply cannot control yourself. (And even then I reserve the right to mutter under my breath in feckless vexation.) I’ve already thought of How I Met Your Mother; anything else?
Oh, and one more thing:
If I wanted to go to TVTropes, I would have done so already.
