I've been meaning to post this for a while. After the Brexit vote, David Cameron hummed a little tune as he walked away from a speech, which a creative person turned into an amusing bit of dance music. I ended up playing it on loop for several hours before it finally drove me to distraction, but it reminded me of some other, similar pieces of work I have also enjoyed.
Warning: ear worm alert.
First, here's Cameron's tune...
Next, Jeff Goldblum's classic laugh from Jurassic Park. I'd watch that movie over and over just to hear him do this again.
Finally, Arnold Schwarzenegger provides a sample that produced one of the most catchy tunes I've ever heard. Don't listen to this one unless you want to be humming it for the rest of the day.
