"Dad I don't wanna go to school today since everybody is gonna be here. Can I stay and home and watch vines?" Peter asks Tony.
"Alright we'll watch some Vines." Tony consents.
"YESS!" Peter shouts. He runs around the living room shouting.
Natasha walks in and Peter runs into her.
"Easy Little Spider." She says in Russian. "What's got you so excited?"
"Dad's letting me stay home from school. Since everybody's gonna be here."
Natasha laughs at the fifteen year old's excitement. "What all are we doing?"
"Watching movies and Vines."
"Sounds great. I'mma go put on pajamas then."
"Me too."
Tony watches the encounter. "FRIDAY have everybody come to the common room. Tell them to wear their pajamas. Just actual pajamas. Not their underwear." The last part is directed to Clint. Last time they had a pajama party he forgot he didn't actually wear pajamas and just woke up and walked into the common room in his underwear.
Everyone has been alerted Mr. Stark.
"Thank you. Don't call me Mr. Stark. It makes me feel old."
Yes Boss.
"Better." He sighs. He turns and walks up the stairs to the penthouse. Peter bounds down.
Tony laughs at his pajamas. They were a gift from a Shuri. They are a onesie. The entire front has a full body picture of Shuri on it. It has a hood that can be pulled completely over his face. The hood has Shuri's face on it. Peter after getting them sent her a pair just like it except with a picture of him in his Spider Suit.
He continues walking up the stairs.
TIME SKIP:
All the Avengers have gathered in the common room in their pajamas. Thankfully no one is in their underwear this time.

In the last prank war Steve took all of his pajamas and left that pair. Tony then proceeded to do the same to Steve. So Steve is sporting an Iron Man onesie.
