Inconclusive Puns

I opened the cabinet to pull out the chocolate syrup when I noticed a chocolate fingerprint on the top. I jokingly asked her if she did that to mark it as hers since she had told me she might have to hide it to keep me from using it all. So, we go back and forth over whose fingerprint it is when she grabs it and takes it over to the dog. She holds it up and goes, "Eddie, look. Whose is that?" Of course, he's a dumb dog, so he just whines and wags his tail. She then comes back to me and says, "I sent the fingerprint to the Lab, results came back inconclusive." Cue long sigh.

Edit: Damn...

Edit 2: The Lab
