At 40 minutes and 23 seconds into the movie...

When Vera Marcal lets Pinky & Cicolini into Mrs. Teasdale's house via a side door, they enter a room. On a wall in the room is a picture, which appears to be of 3 women, and a large tubular object. 2 of the women appear to be naked. One of the women is riding the large object, another is embracing it.

Did I mention the tubular object resembles a large penis?

I am not making this up - freeze frame at 40:23.
