Easter eggs and lols in comments?

Hi fellow programmers, coders, hackers and devs.

Do you put small easter eggs in your projects? Or perhaps add humour in comments to make the next maintainer lol?

I do for sure and it makes my day a little more fun.

Do others also do this? Or am i a unicorn in this sense?

E.g
// this code will self dis-truct unless you clap your hands 5 times.

Or

Press on the footer bottom right and a ninja flys across the screen.

Thanks.
