If it ain't broke, don't fix it. I'm not sure whoever first coined that bit of timeless advice had tight five-minute comedy sets in mind, though.
Regardless, it's advice that comedian Aaron Westberry has taken to heart. In some weird marriage of comedy set and social experiment, Westberry went to a local open mic night and proceeded to tell the same joke repeatedly for the duration of his set. If a good joke is guaranteed to get a laugh, after all, it's only economical to keep using it over and over.
To be fair, the initial joke is pretty good. Whether it's any better the tenth time is wholly up to audience interpretation. At a certain point, you're laughing more at the absurdity of the situation than the joke itself.
