Prior to the Brain Busters/Hart Foundation match at SummerSlam, The Brain Busters won the Tag Team Championship a month before from Demolition on Saturday Night's Main Event.

This SummerSlam was known for one of the most famous wrestling bloopers ever: Gene Okerlund began to interview Ravishing Rick Rude and Bobby Heenan when the background sign fell down, causing Okerlund to yell "Fuck it!" In a shoot interview, Okerlund explained that the interviews were taped beforehand and somebody put the wrong tape in the machine
