Policeman (Doctor Who? 66)

A policeman once noticed vigourously shaking a tree. The policeman asked him what was wrong to which the Master angrily responded that he had locked himself out again. The policeman only looked on at the spectacle, bemused. Unknown to him, the tree was actually the Master's TARDIS and he had locked himself out for the third time that week. (NOTVALID: Doctor Who? 66)
