Who is Todd from Microserfs and what is their importance?

Todd works with Daniel at Microsoft as a software tester. They find common ground in this shared work experience and the oddball humor. However, Todd cannot seem to connect with women for anything greater than meaningless sex and one-night stands. His background also has fundamentalist Christian parents in it, which has left him with an insatiable sexual drive. This changes when he meets Dusty, who becomes pregnant and gives birth. Having the responsibilities of a father, Todd may or may not settle down. Indications are that he is moving in this direction because he feels remorse about kissing a woman in Las Vegas.
