Saw this on the Scrubs forum!
Basically, you say a quote from Will and Grace (a one-liner, just the quote and nothing else unless you want to refer to a previous quote) and then the next person follows it on and slowly you manage to create an entire conversation! (Albeit making not much sense!)
"Ok"?! "Ok"?! Why don't you just punch me in the stomach?! Wow, you just can't hold back, can you? "Ok."?!
