The link wasn’t working on yesterday’s post and it now is. However, here it is again. TEE EMM & PILOT OFFICER PRUNE.

TEE EMM, as previously stated, was the technical manual for the RAF, which contained a huge number of tips on the best way to fly. Pilot Officer Prune was called that intentionally, due to prunes well known laxative effect. As the cartoon states, Prune was to take TEE EMM regularly as it prevented that ‘thinking feeling’.
