Being a dad means finding out your once dainty flower of femininity now passes gas like a linebacker. The dog can get up and leave, but you can't.
Iruka was never truly a masculine man. He wasn't the stereotypical gay either, he just didn't sit around, watch TV, and drink beer. He graded papers and washed dishes. But as his pregnancy went on Iruka started taking on more manly hobbies.
He didn't drink beer or watch sports, although now that he was on leave, he would sometimes watch a game just to keep his mind occupied. He also began to crave beans which caused him to do potentially the manliest of all activities. Pass gas.
It was at these moments when Pakkun would get up. Iruka, bless his soul, never noticed anything and just paid attention to the TV.
"I'm leaving." Pakkun said after Iruka had let one rip.
"No, you're not." Kakashi whispered to Pakkun after checking to make sure Iruka was still giving the TV most of his attention.
"Yes, I am. He's your husband, you knocked him up, now you deal with it."
Kakashi had such horrible summons.
