I'm one of those people who is mostly not-funny, but is occasionally quite funny. I think that if I were given timely material, I could execute it well. I think this would work best with one-liners, where there's less of a need to get the timing right between sentences.

For example, if you'd been having a conversation about Topic A, then later Topic B, and there was a joke involving a double meaning of a word that relates to both A and B. Wrap that up in a one-liner, put it on a Google Glass, and a decent number of people could deliver it well enough to get a laugh.
