[[WMG: Richie and Eddie are Rick and Vyvian]]
At some point after ''Series/TheYoungOnes'', Rick and Vyvian are part of a witness protection scheme and change their names, Vyvian loses his hair or shaves it off after getting over his punk stage. This explains why their voices and personalities are very similar.
* It also explains Eddie's last name. Only [[AxeCrazy Vyvian]] would knowingly take the surname ''Hitler''.
* It seems more likely they take on new identities after having robbed a bank and being on the run.

[[WMG: Alternately, Eddie is Vyvyan's father]]
ExtremeOmnivore tendencies? A violent streak a mile long? Sounds to me the two may be realated. Not even Vyvyan's own mum knows who his father is--it could work. The fact that they both have flatmates named Richard (Rick/Richie) who look alike is just pure coincidence.

[[WMG: Guest House Paridisio Richie and Eddie is the same Richie and Eddie as of Bottom.]]
As part of the protection program, their names were changed. And the 'one bird' mentioned in 'S Up is Gina Carbonara from the film. During the events of their European tour, they wind up broke and end up having to live in Richie's aunt's flat.
