How Long is Long Enough

So I have officially been at my new job for 42 days, and I am curious, my Dear Avid Readers, if you feel that it is long enough to start getting mean. I have this one co-worker named RK (aka Mr. Ridonkulous) and he is the most annoying, angry, ugly, mean co-worker ever. Whenever I ask him a question he just oozes sarcasm. I mean I sometimes sit at work and think of mean things that I could say back to him...for example (this is the conversation that occurred today):

Me: Hi RK, Would a student who is interested in the Doctoral program need to retake the TOEFL?
RK: Do we handle the Doctoral Programs? (sarcasm, sarcasm)
ME: I guess NO???
RK: Why would I know about something we don't handle?
ME: So, we don't even answer questions about programs we don't handle
RK: Why would we? It goes to the person who handles them
ME: Well who would that be then RK?
RK: John Dory...

Now, after this conversation I sort of re-imagined it going more so like this

Me: Hi RK, Would a student who is interested in the Doctoral program need to retake the TOEFL?
RK:Do we handle the Doctoral Programs? (sarcasm, sarcasm)
ME: I don't know, do we?
RK: Why would I know about something we don't handle?
ME: Good question. I'm not sure, but if I had to guess I would say it is because you are anal rententive and you actually know the answer but just like to act like a dick vein and throb uncontrollably when being asked a question because of your alpha male ego doesn't know how to put itself in check? (smile innocently as if my question is totally legit)
RK: Give it to the person who handles it!
ME: I'll handle you!

Ok, so maybe 42 days is too soon to have conversation 2 happen but lord knows I am dying to get to the point where I can say something like that!....so Dear Avid Readers, what do you say, maybe day 62?
