The IT crowd 

The IT crowd is a sit-com about a woman that starts a job in the IT department with no knowledge of what she is meant to be doing and then finds out that only one of her other colleges has any idea about what he has to do.

Characters: one of the characters is a typical computer geek but the other two characters don't have a clue what they are doing and are not very good at their job.

Theme tune: the theme tune is very computerized and the opening sequence is very much like being on a computer as it has clips of a computer game in it.
