Quote from Chandler in The One with Rachel's Date
Chandler: So he calls me Toby once in a while. What's the big deal? It could be worse. It's not like he's calling me Muriel. Ross: Muriel. Why would he call you Muriel? Oh, my God. Chandler "M." Bing. It's not just an "M." Your middle name is Muriel! Chandler: Ssh. It is a family name. Ross: Chandler Muriel Bing. Boy, your parents never even gave you a chance, did they?
