It's Surprisingly Clean

Interpretation: PRB THS = Probe This

Man, I love reader emails. You guys are really fantastic. This little piece of greatness comes from Matt S. I believe this is our first from Missouri. He writes:

In college one of my roommates (and still a good friend) had a Ford Probe that he loved. His creative vanity plates are attached. I actually thought it was pretty clever. I snagged the picture from the Internet Archive (Wayback Machine). The picture is several years old, and he no longer owns that car. Hopefully, you'll feature it...

Your wish is my command. This one is very punny. It also reminds me of this scene from The Office:

Michael: First guy says, "Well, I'm an astronaut, so I drive a Saturn." And the second guy says, "Well, I am a pimp, so I drive a cheap Escort." And the third guy says, "I gotcha both beat, I'm a proctologist, so I drive a brown Probe."

Christian: Ohhh no! [laughs] Oh my God, that's funny! I almost had Awesome Blossom coming out of my nose!
