Tony & Natasha
If he could think of a thing to market, it was done. Including doggy Iron Man costumes for Halloween. There was an Iron Man themed cat collar too. Merchandising was a great thing, and even if stuff went wrong for them, the cash kept raking in and filtering off to everyone's financial accounts. The Ben & Jerry's licensing was a consistent paycheck.
"Good luck there," he said. "Let me know how that goes. I don't think that exists."
Actually, deep down, he didn't want something like that to exist. Tony wouldn't hate being stuck at home as Mister Mom all of the time, but he also wouldn't ever be able to give up tinkering on the suits, or any other of the 1001 projects he had in his brain. He'd miss being a superhero too much, even if they did fail from time to time.
"Sounds like we're damned if we do and damned if we don't this new year," Tony said, after a moment of mulling over things, himself. He made a little toasting motion with his own champagne glass before holding it out to clink against Natasha's. "So here's to the happy parts."
