OP's story is successful.
I'd purposefully create these situations as a teaching aid. For example, I'd deadpan, "It gets excitatory stimulation. If it is stimulated to threshold, it goes off, cannot be excited again for a short time, and then is more difficult to excite until it goes off again until it has recovered." Let a beat pass. Wait for everyone to finish laughing. "That's how action potentials in neurons work. After the neurotransmitter binds..."
A biochem professor of mine used, "So the enzyme comes along and just says, 'hey, baby, I just want to dehydrogenate your substrate with my active site.'" We actually sold t-shirts with that quote to raise money for a student who developed cancer.
Yet another professor had two. "I'm a geneticist. My wife's a psychologist. We have twins. We don't even need to leave the house for our experiments." Beat. Cue half the class laughing, half quite confused. "The tissue they used for that cloning experiment came from the original sheep's mammary tissue. Why do you think the clone was named Dolly?" It went right over quite a few people's heads.
Conclusion: computer science geeks are geeks. Biology pervs are pervs.
