To be honest, it really depends on my mood.
If the humor is based on a myth or untruth or stereotype about an activity or use of a toy I tend to get annoyed because I think it somehow perpetuates the myth instead of resolving it. Gosh, I hope that makes sense.
If the humor is used as an infantile response, I really get annoyed. But, if it's meant to ease into the idea of something without being tasteless or stereotypical I say bring it on! I try to be clever more so than humorous.
