Imagine you and Thor’s wife got in a bet with Thor and Loki (a game or a battle) the losers would have to do whatever the winners decide. The girls win, so you said “Why don’t we make them wear dresses? Like that Midgardian legend when they had to disguise as brides to recover mijölnir” 

“I don’t like your wife anymore brother” growled Thor in annoyance 

“We got into this situation because of you, oaf” replied Loki.

When they return wearing the dresses both of you tried to suppress the giggles, but when Thor’s wife said “my-my, I think you would be a better Allmother than me Honey” You feel yourself starting to laugh.
