"I'll whisper in your ear, you fucking pig."
It's a little joke that got a bit stretched out. Your husband, Vladimir Makarov, was indeed a serious person. Joking with him was incredibly boring because he took jokes seriously and had to explain every word of yours.
If he was tired, you could even end up arguing over a trivial joke. For example, like now: you quarreled during the day, and it was serious enough that Vladimir didn't even leave his office. Well, who cares.
You're not to blame for him being so serious. The whole day passed in silence between you. Only at night, when you lay down in bed, you thought that Vladimir probably wouldn't even come to sleep and would stay in his office. With that thought, you fell asleep.
But in the middle of the night, you felt your husband’s body behind you. He hugged you around the waist and pulled you close, whispering in a slightly hoarse voice: — "Sweetheart..."
With a satisfied grin, you turned to him, and being close enough, you whispered in his ear, barely holding back laughter: — "I'll whisper in your ear, you fucking pig."
While Vladimir blinked in confusion, you just burst into laughter.
