This is the 100th episode.
At the beginning of the episode the names on the Pest Control truck and the store next door refer to the fact that this is the 100th episode of the series. The truck advertises "Pete the Centipede Enemy," and workers are hanging a "100 Cent Store" sign next door. The episode also dispenses with the traditional opening title sequence, so this is the first time the neighboring store is seen being occupied during an episode, and not just in the title sequence.
This is the first time the employee bathroom is mentioned.

The title of this episode, "Glued, Where's My Bob?," is a reference to the title of the stoner comedy film Dude, Where's My Car? (2000).
