I didn't see (an active) thread like this, so I'll just open a new one.
This thread is aimed at double entendre lines found anywhere you wanted to share.
Currently, I'm watching "Alien Covenant", and there's two synthetics (the Fassbender robots) talking to each other, one learning the other how to play the flute. And there's the line "[now you try,] let me do the fingering." I'm a bit tipsy and had to laugh out loud.
