Zoro has no problem speaking with things in his mouth. Sanji on the other hand...

"Sanji hates Usopp right now, everything is completely his fault and he hates him. He hates his stupid face, his stupid lies, his stupid nose and most of all his stupid PLANTS!"

In the end, getting Law to agree to spending the night with them had been the easy part. Knocking down a few of his walls was going to be much more difficult. Law/Zoro/Sanji

There was a hook in the Cook’s galley floor. Zoro should've ignored it but it's not like he's all that good at keeping his mouth shut around Sanji.

Zoro would thank Luffy for introducing him to Law all those months back, if he ever dared to tell him why in the first place that is, but their mutual friend didn't have to know what kind of relationship they had developed. Only him and Law would ever know what happened behind that door everytime Zoro would visit. (or Law and Zoro having a rough session in the BDSM room)
