You know how people have pinboard or sticker maps with all the places they've been marked with coloured pins? And maybe places they want to go? Clint and Natasha have a map, which started out as a joke and was on the wall of Coulson's office or a SHIELD breakroom, but has migrated to the Avenger's Tower or elsewhere... Anyway, they have this map. With all the places they've been shot, stabbed, fallen from high places, fake married someone, fake married each other, been arrested, broken out of jail, been banned by that country's government, been banned from going to again by Fury...
