I work at a big plant that brings in ingredients like milk in big tankers and there are 15-40 people in the plant (which usually is up and running 24 hours a day, minus downtime here and there for cleaning) working at machines that package half+half creamers, 1/2 pint milks, bags of vanilla soft serve ice cream for Burger King, McDonald's, Friendly's, amongst many others.
I play the 'world's smallest congas' while I'm working on half+half creamers in the Lab, testing to make sure they're fit for consumption. The other day things got REAL wacky when I taped them to my ears and gave people a solid "What?" look.
My favorite goofy moment is sticking disposable pipettes in my ears, nose, and in my mouth like walrus teeth and asking people, What Do I have something on my face?
