In "Jackass Presents: Bad Grandpa," Irving (Johnny Knoxville) sets out to sow his oats after being in a marriage for 50 years that hasn't quite worked out.

But that's only part of the story, because all the extra footage that didn't make the prank-heavy original is premiering on MTV as part of "Jackass Presents: Bad Grandpa .5" June 15 at 10 p.m. ET.

What better way to get ready for this momentous occasion than to watch seven videos of Johnny Knoxville talking about his penis?
