Odd men out (Posted on 2015-04-29) Difficulty: 3 of 5
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.

19 is the only prime
33 is the only repdigit and the only palindrome
69 is the only one you can turn upside down and have it retain its meaning
72, being the only multiple of 12, is the only measurement in inches that's an integral number of feet.
98 is the only one that's a measure of normal body temperature in any common thermometric system (latest studies show normal is 98.2, not 98.6 F, the latter being merely an over-exact conversion of the rounded 37 C)
