It was always funny (for me anyways ) when they brought the drug dogs in.
A kid from my high school took a case involving drug dogs and strip search all the way to the Supreme Court and lost (451 US 1022). I was a senior at the time. Yes, I'm old. Anyway, the dogs were so incompetent that they 'hit' on my Calculus teacher's car. I remember the scene of him having to remove his hub caps while the Keystone Kops searched for drugs. My math teacher was definitely not a pot head. More of a Pat Boone guy.
You young guys can google Pat Boone. He makes a cameo in Wierd Al's 'Gump' video.
