For every one example you could list from the IM series, you could easily find many more in the transformers films.
Off the top of my head: the *********ion joke from the first film, the oogling of the robots on Megan Fox, the mom freaking out on pot brownies, the handjob joke in the newer one, the out of place mouth wash joke, and the biggest offender, the giant clanking metal balls on the robot in the second film.
Are you really going to try and tell me that these movies don't go for a more infantile approach in their comedic bits? I know words like "infantile" and "immature" are all subjective but I really feel like most people would be on the same page with this one.
