While its humor can be hit-and-miss, the whole purpose of the Hero Factory FM radio show "podcasts" is to be funny. The jokes mostly come from the carelessness (and at times, incompetence) of the host and the confusion that always seems to pop up between him and his interview subjects. Funny Oh Crap moments also occur, like when Alpha Team Leader Preston Stormer threatened to tear his arms off after the host had dropped a brick on his secret Berserk Button.
The entirety of Podcast 8, especially the sneak peak at the musical.
Some of the missions on the Mission Ticker can be humorous:
"There's someone on my roof! Oh, wait... it's Santa Claus. I hope."
