Is it funny, though? It just seems completely random, and laughing over random words is something I've only ever associated with the young, sleep-deprived, or stoned. There's no wordplay, no build-up, none of the halmarks of an actual jest. It's just "Hurr, hurr, doodie gift sounds funnier than stool sample". That kind of thing is typically only offered as comedic fare to those of similar mental states, or as an in-joke. Sometimes it can have humorous impact simply by blindsiding someone, but that only serves to further detract from narrative flow, as you noted.
In short, the attempts at comedic effect aren't necessarily the issue, it's the complete lack of effort put into it [especially when considered against other translator groups, who tend towards having full gag sentences in their translator (margin or end) notes, which generally goes over better in both effect on flow and in having a comedic impact].
Of course, in a sense, it's down to us having to accept whatever conditions the translators set, as part of the process of accepting the gift of their otherwise capable translation. On the other hand, the same is true of going into a shop to buy food from an unclothed, unbathed individual. Even if we're willing to do it [What would
you do for a Klondike Bar?], the presentation indicates that the individual's focus is on their own indulgence rather than in presenting their offerings in a way that is intended to connect well with others.
Well, so far the tweaks have been minor enough to not hit the "vagabond grunge gastronomy" level [actually, it'd be a bit concerning if
any translation ever makes it to that level of comparison], but it really seems like a sharp detraction from the translation quality for absolutely no compensating benefit.
To
tl;dr, either Arcky needs new meds, more time spent on their jokes, and a fresh baked cake [y'know, for the
rest of their translation work], or we need to accept that this team's translation is going to cater to a specific 4th wall breaking niche.
That said, if Arcky is going to continue with his current approach, he still is lacking in suitable commitment. Nargberries and Plonker are both alternative terms for the respective dangly bits down there, and both are objectively funnier options than pee pee. I refuse to give credibility to any opinions to the contrary.
