one man's lobster is another man's fish (or something like that)

Logan and I had an argument tonight over the Red Lobster logo.

me: Look, Logan, a lobster!
Logan: No, it's a fish.
me: No, that's a lobster.
Logan: No. It's a fish.
me: Logan, that is a lobster. Look at his pinchers.
Logan (firmly and VERY seriously): No, mama. it. is. a. fish!

I gave up at this point mostly because I was laughing to hard to continue the conversation.
