Then of course there are those that sing, cuss, fart, play ringtones on 121.5.......
This is buggin' me... how on earth can someone do such things on the freq without the intervention of the other pilot? How can a person be called a captain of an a/c when he allows the FO to behave like that, or worst, if he does it him(her)self?? And if an FO sees that from his flight deck superior and says nothing what are the chances of the very same FO taking control of the a/c if some difficult situation arises, just because he/she feels intimidated?
