Love Lab Puns

but I was afraid that I'd get the wrong reaction.

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

Because science is a lab or a love

I work as a lab tech in my university, and as I was preparing some bacterial streak plates for some students (mind you, we use an innoculating loop to transfer bacteria from a sample tube to plates), I said to some of the students: "what did one bacteria said to the other? Let's get looped, and go streaking."

I received an uniform look of dissapointment and a couple of facepalms from the students while I giggled at my joke. The teacher loved it though.
