Doug Mellard: Prophylactics

I remember one point, this older gentleman asked me for some prophylactics, and at that time, my sexual vocabulary wasnt that great, you know. So, Im checking my word bank for the closest thing I have to prophylactics. Closest thing I got -- pterodactyls. I was all confused. I was like, Excuse me, sir, I hate to break it to you, but those things have been extinct for 65 million years.

Sir Barnes Wallis

Born 26 Sep 1887; died 30 Oct 1979 at age 92. Sir Barnes Neville Wallis was an English aircraft designer and military engineer whose famous 9000-lb bouncing “dambuster” bombs of WW II destroyed the German Möhne and Eder dams on 16 May 1943. He designed the R100 airship, and the Vickers Wellesley and Wellington bombers. The specially-formed RAF 617 Squadron precisely delivered his innovative cylindrical bombs which were released from low altitude, rotating backwards at high speed that caused them to skip along the surface of the water, right up to the base of the dam. He later designed the 5-ton Tallboy and 10-ton Grand Slam earthquake bombs (which used on many enemy targets in the later years of the war). Postwar, he developed ideas for swing-wing aircraft.«[Image: Wallis at his drawing board.]
