 While playing with fireworks he caused a lorry to swerve, and crash into his house where Melanie was sitting watching television; luckily, she was not badly hurt.After this incident Tinhead had a change of attitude, and with encouragement from Sinbad, tried to join the Army.Tinhead passed the entrance interview and test with flying colours and really looked forward to life in the army, but was very disappointed when he arrived at the training camp only to be told that he could not join the Army after all because of a problem with his hearing.
