Giraffic Jam

Alright listen up, genius. You see, a "traffic jam" is when there's a bunch of cars all stuck together on the road. This joke uses "giraffic jam" which sounds like "traffic jam," but it's about giraffes. The joke is funny because it's unexpected and plays on words. You probably didn't know that the average person spends about 42 hours a year in traffic. Maybe if you spent less time breathing, you would learn something. Do you know what the opposite of genius is? You.
