When Tumblr user gay-undertones's sister left her bedroom/shrine to One Direction open and unguarded, she did what any good sister would do...
gay-undertones: "I thought 'why not cut out 350 shrek faces AND MAKE EVERYTHING SHREK'"
"I PRESENT TO YOU ONE DIR'SHREK'TION!"
"No face left uncovered."
Her sister's reaction? Not pleased.
