If you're a curious, here's what the other options do:

Smell it:

: Trevian!

Huh? I don't know what this means. It doesn’t sound Japanese.

I am going to assume its French, and Hiro actually said ‘Très Bien’ which means ‘very good’

So to summarise… Hiro thinks the sex aid smells very good.

Wear it:

: Ugh!

XXXX! (that loud, sharp censoring noise again)

: It’s a turtle!

Oh my … I will let you use your own imagination on that one.

Throw it away:

: I can’t be bothered with this.

…I don't think we should be either.
