Y is for Yogurt

yogurt (noun):  a slightly sour foodstuff made from fermented milk, sometimes eaten plain and sometimes with sugar or fruit added. Alternatively spelt yoghurt in some countries. 

Yogurt is mentioned several times in Scriptures, translated as curds in older translations. In ancient Middle Eastern traditions, milk was cultured and fermented to preserve it, yielding a yogurt-like food. Some modern English translations use the word yogurt to make the culinary imagery clearer for modern readers.

Finally, Yogurt is one of the major characters in Mel Brooks' SF comedy film Spaceballs, being a parody of Yoda from Star Wars. He is played by Brooks himself.

W is for Winnebago (Eagle 5)

An unusual one, this. This spacecraft is in fact a 1986 Winnebago Chieftain 33 with wings attached, forming the 'Eagle 5' spacecraft. It comes complete with a periscope, secret hyperjets and an infrared scanner.

Spaceballs is a 1987 comedy film, co-written and directed by Mel Brooks. Essentially a parody of the original Star Wars trilogy, it also made references to the Alien and Planet of the Apes films.
