I love spoonerisms: ‘ducking felicious’ and ‘rucking fidiculous’ are a couple I’m rather proud of. For me, the spoonerism’s appeal harks back to the music hall days where sexual double entendre was lapped up by audiences who wanted to hear something naughty being alluded to without hearing any actual filth.
A present day business presentation is a similar scenario, where foul language of any kind will be highly inappropriate. However, using the same old safe cliches and turns of phrase immediately confirms to the audience that they won’t hear anything new or interesting.
No-one on the cruise expected a husky to enter the pool.
So, surprise them. Throw in something odd to see if they’re paying attention*. Use a spoonerism to conceal a rude word, put in an image of you wearing something ridiculous, or start describing what someone in the audience is doing. Do something original; they’ll thank you for it.
*You can do the same with a document that you think no-one will read. In the middle of the largest paragraph, put in something fun such as an offer to make the reader a coffee if they come to your desk and say ‘octopus’. For example.
