No, they use a laugh track. One paying attention can notice the exact same laugh in some scenes.
it is a comedy
do you agree with the statement in the second verse that children laugh in mirth at others tears? give an example
We laugh at jokes because when we see or hear funny things we are forced by our body to laugh.

A conventional sitcom is traditionally family-oriented and with a laugh-track. One in which the story-lines are usually pretty standalone and with little to no major ongoing plot threads. The status quo is usually the same by the end of each episode. A non-conventional sitcom is one which goes against these rules to some extent. No laugh-track for example, or breaking the fourth wall. Also, developing plot-lines and characters. A good example of this would be How I Met Your Mother, or Friends, where the characters go through major changes throughout the life of the show. I'd say Scrubs is a non-conventional sitcom in that it plays around with different kinds of humour (slapstick etc), has no laugh-track, utilizes a voice-over and even down to the fact that it's set in a hospital rather than a domestic family situation. All of these factors point towards non-conventional over conventional. Hope this helps. :)
