They Go Boom!

'They Go Boom!' is a 1929 American comedy short film, starring the comedic duo of Stan Laurel and Oliver Hardy, known together as Laurel and Hardy. It is their thirty-seventh film together and fifth talkie. In the film, the pair have difficulties sleeping in their apartment due to Hardy's cold and Laurel's snoring, eventually including trouble with their mattress. Attempting to blow the mattress up manually by blowing into a connected hose, Hardy accidentally inflates due to air going from the mattress into Hardy. The effect is achieved behind the scenes by inflating the midsection of Hardy's outfit.
