how is that even an option?

When a choice someone makes has no logical or acceptable reason why it was made and you have to question how it even became an option before said choice was made.

John: That lady at the gym with a mustache can bench 300.

Larry: She has a mustache? How is that even an option?

Potato Bob: So yea, I got a pet Dandelion the other day.

Larry: ...How is that even a option? Of all the pets you could choose from you got a pet plant. You could have got something normal like a cat, a dog, a bird or even something a little different like a ferret or pig but you chose a motherfucking Dandelion? QUESTION FUCKING MARK. THE FUCK IS YOU TALM BOUT?
