Others posted but I went through the checkout carrying only a bottle with "Lubricant Laxative" in big letters on the label.
I think I'll just let them sit for a week and then take an after photo. Since my photography skillz are rather limited, I will take a scan as well as a regular photo. The scan is easier for me to control the settings. This test will answer everyone's questions.

...well, actually it won't but I hope it's entertaining.
