I read the thread about "might as well have" on a website. But I still don't understand the last sentence in the following text. Would you please tell me what the last sentence means? Thanks!
Rachel: I know, but y’know condoms only work like 97% of the time. Ross: What? What? What?!! Well they should put that on the box!!! Ross: Well they should put it in huge black letters!!!! Rachel: Okay Ross come on let’s just forget about the condoms. Ross: Oh well I may as well have!
