Tommy Flint

From Tardis Wiki, the free Doctor Who reference

Tommy Flint was a student at Coal Hill School in 1963. On his last day at the school, Ian Chesterton confiscated bangers from him.

These remained in Chesterton's blazer pockets over his travels with the First Doctor. He remembered, and used them as a distraction when dealing with the Master aboard the Doctor's TARDIS. (AUDIO: The Destination Wars)
