I'll Have What He's Having
You see someone doing something stupid and you decide to be just as stupid because you're too lazy to think.
My cousin started singing in the grocery store. I said, 'I'll have what he's having.' Now I sing in the grocery store.
My teacher started eating chalk. I said, 'I'll have what he's having.' Now I eat chalk and my grades are terrible.
My neighbor started yelling at a pigeon. I said, 'I'll have what he's having.' Now I yell at pigeons and I'm not proud of it.
