Annoying Guy

So I'm a team member on this project at work; the project goes like this: 6 days of full day meetings where the 12 of us (team members) are discussing, analyzing, and documenting a certain process in our work place to improve it. It is a lot of mental work and heated discussion!!
After the six days, the elected team leader would present the project and the action plan to the executives, and after approval, he/she would lead the implementation of the change to improve the process.
The daily team meetings are full of discussions and sometimes opposing opinions; the discussion was carried out in a respectful and organized way, even if one was trying to make out a point that EVERYONE is wrong! Which was good...

So the team members were selected by their departments executives/senior managers; and one of the members is a receptionist aka "annoying guy".
Annoying guy was not really annoying to me until this happened: we just came back from a short break last Wednesday, and the facilitators were trying to get us to come work on this project on Thursday. I told them, I would love to, but absolutely not, I have lectures and a quiz this Thursday in Bahrain. I said, I'm not coming! He replied: if you're not coming, then who will attack? (He is implying that I am attacking others when I am discussing problems with the process and asking them questions and requesting explanations, I was pretty active :p)
I was shocked because, not only he thinks he is all that and that his receptionist experience qualifies him now to discuss medical stuff (he actually "apologizes" for using the medical terminology), now he is trying to look important by this nice question, who will attack?
I was so annoyed, so shocked of such childish behavior coming from a man who has double my working experience. Fine! I smiled and told him that I am not attacking, I am working for the hospital!
His comment was annoying. But I chose to ignore it for professional reasons. Then on Saturday, I was speaking to the group, making a serious comment about an issue that was raised up, and he interrupted me when I first started, and he repeated the word again in front of everyone (go on, attack!). I stopped talking, turned to him smiling, and said "thank you (flan) for your NICE comment" and I turned to the group with a totally serious face and went on talking. Nobody looked at him again, I was able to pull their attention to me thanking him for the word that he said, and then pull it back to what I was saying. It was like, when there is a child shouting and you give him a cookie and he shuts up!
I ignored his behavior not because I could not answer him, wallahi I have nicer come backs, but I rather not reduce myself to his size.
After we finished the discussion, he told me "I am just kidding! You are serious since morning?!" I told him seriously, "that was NOT nice". Period. Ignore. He repeats, I repeat and then ignore. Ignore, ignore, ignore...

Annoying guy disrupted and interrupted most of us, most of us think he is either annoying, or just a person who is ready to clown around at any time. We all despise it when he turns to pretentious mode and pretends to know it all.

He is so annoying, I keep ignoring him whenever he throws another nice comment. And I don't think he would dare give me one of those anymore, because he knows that I will smile and thank him and make him look like a fool.

He got to the look-at-me girl, she got so annoyed that she really got upset about some stupid thing he said. I told her since day one to ignore him, because we are a group of intelligent people, and we will certainly not give weight to whatever foolishness he blurts out. She didn't listen to me and she argued with him.

Isn't he annoying? :p
