Soda Popinski's laugh and Ganon's laugh on the NES

[Kakariko Kid]

Soda Popinski's laugh when he knocks Little Mac out in Punch-Out!! Featuring Mr. Dream and Mike Tyson's Punch-Out!!, is the same laugh Ganon has when a game over occurs in The Legend of Zelda II: The Adventures of Link. The difference in them is Ganon's laugh is slower.
Also, Zelda 2 and Mike Tyson's Punch-Out!! were both released in 1987.
