How to lose a smelly friend

Equipment

1 MRT Train

Method

1. Walk your friend towards the train.
2. Dilly dally outside the train, then tell your friend that you will be boarding.
3. Make sure that your friend enters the train carriage. Pretend to walk in behind him and stay near the door.

Observation

This trick works. The last time someone did it, the train carriage started to reek the minute the doors closed.
