You can't call "remove" with multiple arguments, you can only remove one thing at a time. Also, inside the argument list you've put "messy_list" followed by parentheses containing an argument, which is the syntax for calling a function or method. That's why the challenge is telling you "Bummer: TypeError: 'list' object is not callable"

The argument to a "remove" call is simply the contents of the item you want to remove.
