All of us should know by now...in dear alf, alf uses corner pictures related to the questions. Someone asked about the Vykkers stiched up legs, so Alf answered, and put a picture of their legs at the top.
No, I meant Oddbutt. No I'm j/k. Yeah, it pretty much looks like a shower curtain as the vykkers loin cloth. If they don't have any sexual organs, why cover up there?
