bing-bong
Explanation
This comic is a brief, sharp joke about faking orgasms, delivered with an absurd twist on the concept of "planning ahead."
In the single panel, a woman tells a man at their front door: "Before we go to bed, I should tell you, when I have a very powerful climax, I say 'bing bong bing bong.'" She is essentially warning him about a distinctive vocalization she makes during orgasm. The man, looking slightly puzzled, asks: "Like a doorbell?" She confirms: "Like a doorbell."
The caption below delivers the punchline: "With advanced planning, it was much easier to fake multiple orgasms." The joke is that by pre-establishing that her orgasm sounds exactly like a doorbell, she has set herself up to fake orgasms effortlessly -- she can simply say "bing bong bing bong" at the appropriate moment and her partner will believe she is climaxing. The "advanced planning" refers to the fact that she announced this ahead of time, so when the obviously fake-sounding noise occurs during sex, he will not question it.
The humor works because the described orgasm sound -- "bing bong bing bong" -- is so obviously mechanical and unsexy that no one would naturally make it during sex. Under normal circumstances, if someone suddenly started making doorbell noises in bed, their partner would be suspicious. But by preemptively framing it as her genuine response, she has created plausible deniability for what is clearly going to be a performance. The comic takes the well-known phenomenon of faking orgasms and adds a layer of strategic premeditation that makes it both funnier and slightly diabolical.
The title "bing-bong" is simply the onomatopoeia for a doorbell, which reinforces the absurdity of the premise.
