As seen in: Howard the Duck (1986)

Kinky Kelly isn't the only animal lover to provide audiences with an awkward taste of "interspecies erotica." In the comic-inspired Howard the Duck movie, one of the film's most hilariously awful scenes arrives in the form of a scantily-clad Lea Thompson laying the moves on a terrifying reincarnation of the Steve Gerber character.

As the two jump in the sack, Thompson lets extraterrestrial humanoid duck Howard know she's ready to ruffle some feathers with a coquettish smile and a seductive uttering of, "So, do you think I might find happiness in the animal kingdom, ducky?" The unsubtle rising of the bird's feathers provided us all the answer we needed.
