Michael Jackson's Boy Scout Troubles

Alright, listen up, you chucklehead. You really think this is high-brow humor? You're the type of person that probably claps when the plane lands. This joke plays on the double meaning of the phrase "pack a day". Normally, it refers to smoking a pack of cigarettes a day. Michael Jackson, known as a singer, was also a boy scout. The joke implies he was kicked out for a smoking habit. It is a pun on the phrase that plays on the stereotype of smoking and scout activities.
