Bob Waite is the head custodian at Greendale Community College. He is a politically savvy head custodian who’s not afraid to get his hands dirty but is smart enough to wear rubber gloves. Bob has to contend with Annie Edison and her Criminology Professor Buzz Hickey who are navigating Greendale’s corridors of power. He is portrayed by actor Nathan Fillion.
Bob Waite meets Annie and Professor Hickey at a custodial mixer and recognizes their names from the work order they submitted to have a bulletin board rehung. They want to expedite the process after hearing it could take up to six months. Waite shows them his computer which displays a "banned website" message and explains that a lot of the websites his department likes to visit are blocked at work. Waite then suggests that if Annie and Hickey are able to remove the web restrictions he will move their work order to the top of the queue. After some wheeling and dealing, Annie finds a way to have the restrictions lifted but decides it isn't worth the favors along the way. Later, Waite tried to access a particular websites but it was still blocked ("Analysis of Cork-Based Networking").
In the 2015 semester at Greendale, Bob Waite made an appearance at the secret Speakeasy created by members of the Save Greendale Committee. He was seen in a corner booth talking with Jeff Winger and offering the services of his custodial crew to clean the bar. Waite also seemed to be trying to leverage the deal by threatening to expose Jeff's operation if he didn't agree. Jeff asked if he was trying to blackmail him but Bob simply said he was just talking shop ("Ladders").
On September 12, 2012, actor Nathan Fillion visited the set of Community and met with the cast while they were shooting ABC show "Castle" which was filming next door on the same Paramount lot where Community was shot at the time. He would later tweet this message on his twitter account accompanied by a photo of him with The study table:
“I’m officially in love with all the girls on #Community. Even @kenjeong. Especially @kenjeong.””
