In the episode "Mr. Griffin Goes to Washington" there's a scene which has always left me baffled; Peter is in a courtroom, chokingly giving testimony about being showed lewd pictures by Clarence Thomas (no doubt in reference to one of those judge/intern sex scandals...I've long since deleted that particular case from my internal hard drive) but at the end, when confronted with irrefutable evidence to the contrary, he suddenly seizes the microphone and blurts out "Ba ba booie! Ba ba booie! Howard Stern's penis! Ba-ba booie!"
To what does this latter part refer? Surely it must reference something, (no doubt to do with controversial radio personality Howard Stern) but the Family Guy Reference Archives fails to mention it.
Just one of those inane things I must know.
