In MGM's 1930 Laurel & Hardy film, Murder Case, the boys discovered a newspaper notice that a very wealthy man by the name of Ebeneezer Laurel died leaving a very large estate. Interested parties were directed to go to the Laurel mansion for a reading of his will. Stan did not remember whether Ebeneezer was one of this relatives or not but thought it worthwhile to check out. In the meantime, it was discovered that the man was murdered. The police were involved and sought to gather all the Laurel relatives, including Stan, for their investigation.

Upon arriving at the mansion late in the evening Stan and Ollie were directed to spend the night. After changing into their nightshirts, the boys settled in for the night. Their guest room was actually the place in which Ebeneezer was murdered. Frightened from various noises, a pair of eyes, and screams, the boys panicked and ran around the mansion in their night clothes closely followed by the police. Stan and Ollie soon discovered they are in deep trouble:

 When a cop ran out the door, he created an updraft that scooped Stans nightshirt up and over his head revealing the union suit he always wore underneath. 

An embarrassed Stan quickly pulled his nightshirt down over his long underwear.

Murder Case was directed by James Parrott and produced by Hal Roach. It was the first film in which Hardy said his famous line “Here's another nice mess you've gotten me into.” Many believe he actually said “fine mess” but it was actually “nice mess.”
