Actually, it WAS in the manga:
^It's just Nami's line that was absent. I guess the anime will add that in though, heh.
Oh, and a couple more nuggets of info popped up, in addition to what electricmastro posted:
-Between Shanks and Beckman, the former is more popular with the ladies, but the latter is the more flirtatious of the two.
-Ranking of which Straw-Hats are the heaviest drinkers:
-Oda clarifies that Ryokugyu doesn't need to eat since his DF power allows him to directly absorb nutrients (recall him telling Fujitora at the Reverie that he hasn't eaten for 3 years...).
-And last, but not least.... official colors for the Vegapunks!
