role profile "canned laughter device"

Some people are very funny, are laughing day and night although life or the project situation is not comic. I'm sure fun has to be a big part especially also for IT projects. Why acting like being on a burial. But don't forget to set your communication on a serious baseplate, being reliable and honest to yourself and your environment.

I know some of these "canned laughter device" candidates ... one of them I saw in front of the Kölner Dom some days ago.
