I was given an "odd man out" quiz, which definitely admitted more than one answer.
I have slightly modified it to make it even more ridiculous.
Please comment on the following set of numbers:
19, 33, 69, 72, 98
Choose the possible options for "odd man out" and justify your choices.
By the way, if you asked which of these numbers was "the special one", then I think a case can be made for any of the five. Every number is special in some way, not unlike people or snowflakes.
