Try to not think about penguins
(Amusement Potential: 1-5 minutes)
This is especially hard, because by trying too much, you remember what you were trying to avoid thinking of. If you try too little, you end up thinking about penguins anyway.

Use your secret mind power
(Amusement Potential: 5-10 minutes)
Pick a passing by and try to use your mind power to command them do something, like drop their bag or knock into someone. The law of averages dictates that sooner or later one of your mind commands will come true, so you can convince yourself that you really have super human powers and waste even more time trying them out.

Try to swallow your tongue
(Amusement Potential: 1-2 minutes)
There's not much to say about this one. It is possible, but really stupid.

Hahah, den sista är roligast. Inte att göra alltså, hade jag lyckats med det hade jag nog dött!
