H/t to this Redditor who came up with the genius idea.
This girl's boyfriend and his roommate made a couples costume*, so she dressed up as a Third Wheel...
*They're both "ceiling fans."
And spent all night photo-bombing other couple-costumes. Here she is with Mario and Luigi.
Two in-love hippies... And a third wheel!
An attractive doctor and nurse couple... And a thrilled third wheel!
