The vibrant after dinner speaking scene demands originality because the internet has made everyone all too aware of just what poor one liners are all about and how not to use them. Nothing will compromise your speech more quickly than relying on google for your humor. They’ve heard them all a million times before and it just disappoints.
There is humor to be found in everything we do, see, eat, follow, love and hate. You just need time to think about it. Classically an after dinner speech will demand some great anecdotes so there’s plenty of opportunity to get some great lines in there. Think carefully about the wording, pace and pauses to give it some humor, and consider how to link these stories in an amusing way. Very often the thread that you dream up to tie them together can be the funniest part.
So, if you’re in the process of googling after dinner speech jokes, then stop. At best they’re weak, not very inventive and unfunny. Instead look closer to home for the real comedy.
