|Interests||Telling Bad Jokes|
|Voice Actor||Fred Stoller|
Mr. Beaker (voiced by Fred Stoller) is another teacher at the kids' school. He mostly teaches science, but has been known to teach other subjects. He tells bad jokes, and often speaks in a dead-pan voice. During the episode when Tommy sleepwalks and steals property around the neighborhood, it's due to the stress of an upcoming test. Beaker claims the test does things to those who take it, showing a picture of himself before it; he was in much better shape then.
