It's just inherently funny to me that they made the 98 anime version of Vash a bit of a pervert, when in the manga he's easily the most sexualized character in the series and the character that gets the most people acting perverted towards him. He wears a tight bdsm style leather crop top and extremely form fitting leather belt pants, has several lovingly detailed crotch shots to the point where "Vashussy" is common verbiage in the fandom, is forced to strip naked or near naked at least twice, and more than one enemy gets aroused when thinking about fighting/killing him. At one point he even gets walked in on while half naked after a shower and goes "kyaa!" while covering himself up like an echi comedy female protagonist. Nobody does it like him.
