It was written by its stars, Rik Mayall as Richie Richard and Adrian Edmondson as Eddie Hitler.
The letter is from the solicitors, which Eddie is left to dispose of, and the parcel contains a blow-up doll Richie ordered without his flatmate's knowledge.
The second act opens with Richie having trouble with Monica; ultimately he accidentally attaches himself to the doll with superglue from the hand cream jar.
The play ends with Eddie realising his mistake, and the pair apparently electrocute themselves to avoid paying the debt that they both now owe.
Rik tries to get the audience to stop laughing by telling them to pretend that they're watching Ben Elton.
A brief gag involving Richie's failed attempt at hiding Monica from Eddie was excluded of all home media releases of the show for unknown reasons.
Rik Mayall is always the first cast member to both speak and appear on stage, shortly followed by Ade Edmondson.
