1 Tap out a tune using your foot on the floor and see how many people join in.

2 Watch the pattern the fluorescent lights make on a bald head. More than 1 bald person? Compare and contrast patterns.

3 Count the squares on the ceiling and practice a bit of multiplication.

4 Make pictures out of the stains on the carpet – a bit like cloud pictures on a summers’ day, but dirtier.

5 Listen in to other patients’ conversations and try to diagnose their ailments.

6 Play a game of elbow wrestling with the patient sitting next to you.

7 Place the skeleton models in obscene positions and see if anyone notices.

8 Turn the doctors’ names into rude anagrams; just remember to use the correct name when you eventually speak to them.

9 Count the seconds between each cough, belch, sneeze and fart.

10 Yawn loudly, then watch the ensuing tidal wave of yawns spread around the room – rather like a Mexican wave of gaping mouths.
