A Hufflepuff, Ravenclaw and Slytherin Walk Into a Bar....
Matching HIMYM characters with their Hogwarts houses
Ted Mosby
Ravenclaw
Ted is sooooo a Ravenclaw, geeking over his crossword puzzles, calligraphy set, Renaissance faire, “fun facts” on architecture, wearing fake spectacles to look smart, and pronouncing encyclopedia “encyclo – paeee – dia.“
Robin Scherbatsky
Gryfinndor
She's quite the independent spirit. I mean, she's wearing the Gryffindor colors right here. If that's not a coinkydink, I don't know what is.
Barney Stinson
Slytherin
Lily Aldrin
Slytherin
She might seem sweet but she's actually sly. 
Marshall Erikson
Hufflepuff
If anyone's the most Hufflepuff, it's Marshall. Marshall is the most Hufflepuff who has ever Hufflepuffed. He's the most puff who has ever huffed. 
All the times he showed appreciation for food.
Tracy (the mother)
Ravenclaw
It's no surprise that Ted would marry a Ravenclaw. You know you're a Ravenclaw when you do quirky paintings of robots playing tennis.
Have a legendary day.
