Sanji is my favourite character and I understand the cultural aspect of it, but yes his gag is the worst. I like to pretend the nosebleed stuff in Fishmen Island never happened.
That isn't to say that it can't work if it isn't toned down and used appropriately. Some of my favourite moments are when it's played straight or not so pervy.
For instance, when Sanji, Luffy & Usopp were going to save the others on Skypiea and Sanji just says "I hope Nami & Robin are okay" with Luffy asking "what about Zoro & Chopper?" in the background.
Or even the Hiyori one with the "my bounty is higher than his" moment.
