'To put it delicately...' What are they talking about?

In the scene where Peter and Tammy are leaving the drugstore, Tammy sees a bunch of "contraptions" in a store window and asks what they are. Pete says "well, to put it delicately...there's no way of putting it delicately."

I rewound the scene a number of times but still couldn't figure out what it was they were looking at in the window. Can anyone clear it up for me?
