College Of Marin Puns

So a little backstory, my parents take the dog for a walk every night. My mom is in college (lol napoleon dynamite) and she takes a marine biology class.

So they were on one of those walks last night, and they were talking about ants. My mom's question was whether or not ants sleep. My dad replies saying, "Why are you asking me? You're the one in a biology class." To which she replied, "I'm in a marine biology class, I don't think there are any marine ants."

Without skipping a beat, my dad came up with the most incredible response...

"Why can't there be marine ants? We already have army ants."
