I had a "marital aid" in my bag once.
It had sparkly silver bits through-out. Very pretty.
The silver glitter showed up on the hand baggage x-ray.
TSA chick ran my bag through. Backed it up. Ran it through again. Backed it up again. Ran it through again. Dude training her said, "No matter how many times you run it through, it's gonna look the same." He had to explain to her what it was. She thought it was a bong. I just stood there smiling.
Whisked me through, and done!
I also had a similar experience with a Brooks saddle. (B68, for those who care.) I told the x-ray guy what it was, "It's a bike saddle," and they let me go without opening my backpack.
