Eh, it's Tuesday

Have you ever noticed that a lot of people answer the question 'how's it goin'?' by telling you what day of the week it is? Examples:

A: "Hey, how's it goin'?"
B: "Eh, it's Monday."
A: "Yeah, that sucks."

or

A: "Hey, how 'ya doin'?"
B: "It's Friday!"
A: "Yeah, I hear that!"

Not only did the question go completely unanswered both times, but Person A found Person B's responses to be perfectly reasonable. So next time I'm in a situation like this, I'm going to change it up a bit. If somebody asks me how I'm doing, I'm going say 'eh, it's Monday' even if it actually happens to be Tuesday. Then when they look at me like I'm crazy, I'll tell them that I feel exactly like I did the day before.
