Schef

Schef was a student who collected the TARDIS in his compression-sack and took it to school for show-and-tell. He was ridiculed for his fanciful story about the box just appearing and was kept in detention after lessons. Yeamorg Warriors attacked the school and were left unconscious when the Eleventh Doctor overloaded their brains. Schef was believed when the TARDIS dematerialised. (COMIC: Finders Keepers)
