I Heard You Using the Microwave 

This means that somebody was too loud during sex the night before.

Justine: Good morning, guys! How did you sleep?
Carla: Not very well.
Justine: why?
Carla: I heard you using the microwave last night..
Justine: Oh dear..

'You're just jealous because you heard HER using the microwave but you can't handle that heat!'

Usain Bolt

Usain Bolt is the greatest sprinter ever.

The tall Jamaican recently went to Beijing to take part in the Olympics. He won gold in the 100m sprint, as well as breaking the world record with a time of 9.68. In addition he also won the 200m, breaking the record there too, with a time of 19.30. With the help of his Jamaican team mates, including the famous Asafa Powel, he managed his 3rd gold medal and 3rd world record by winning the 4x400m relay.

Usain Bolt is well known for his show boating, and extreme confidence before each race. in the 100m sprint final he stopped running 20 metres from the end, waving his hands and beating his chest.

When asked how he prepares before a race, he said "I get up at 11, go and have a Mcdonalds, then go back to bed, and get up an hour before the race".

The Jamican has been tested for drugs over and over again. Always negative.

Usain Bolt should enter himself into every event at London 2012
