Dilbert
The Competition
S1 E2:
When rumors of competition in the field reach Dilbert, he is forced to push up the deadline on the Gruntmaster 6000. The Boss decides they need to increase security, so their progress is not leaked, and puts Dogbert in charge of the new extensive security. Dilbert is suspected of being a traitor and fired from his job, so he takes a job with the rival company. At his new job Dilbert has his own office and is surprised by how smoothly things run. Dilbert innocently suggests a marketing department, which ends up destroying the rival company, and he gets his old job back, minus the extensive security.
