Every Friends Joke

A new Chandler's date left a message for him on Ross's answering machine. Ross is wondering why.  Chandler : I told her that my number was yours because I couldn't tell her it was mine because she thinks my number is Bob's number. Ross (jokes along): Tell me again. What do I do when Mr. Roper calls? /////////////////////////////////////////////////////// Who is Mr.Roper? He hasn't been mention ever before since the beginning of Friends series. But audience seem to get a good laugh about this Mr.Roper-comment. Why? Who is he?

Chandler is planning of meeting up with a hot girl who has mistaken him with some Bob over the phone. Chandler used the situation and and invited her out as a Bob. Ross is doubting that Chandler would manage pretending to be that Bob-guy, once he is present in the girls face. Ross: - You do a good Bob impression... but when she  sees you tomorrow... she's gonna realize you're not Bob. Chandler poses and says in a wired voice: - Ooh, you see Tattoo, Ms Jude's fantasy is to rekindle the love she once had with Bob. What is with the voice? Who is Tattoo? And why Ross is called this way?

After finding a lot of similarities between his life and recently passed away Mr. Heckles's one Chandler freaks out. He thinks he will end up along just like his dead neighbour. That his intollerance to girls' imperfections would serve him bad: - What if I never find somebody? Or worse, what if I found her... but I dumped her because  she pronounces it, "supposably"? My dictionary translates "supposably" just fine. So it is a correct word to use. What is the problem with it for Chandler then?

Guys are reprimanding Chandler for rejecting women over superficial, insignificant things. Ross: - You name one woman that you broke up with for an actual real reason. Chandler: - Maureen Rasillo. Ross:  - Because she doesn't hate Yanni is not a real reason. ...and auditorium laughs, which I don't get. Who is "Yanni"? Is that supposed to be someone everybody knows? What is fun about it?
