Piglet Flu

During times of pandemic, the common flu is known as Piglet Flu. While less deadly than Swine Flu, it still makes you feel like shit. However, because it is not infamous like swine flu, you get no respect from having it. So you feel like crap and no one gives a damn because you don't have h1n1.
Doctor: How do you feel.
Patient: Like shit.
Doctor: Well the tests came back, you don't have swine flu. So get the hell out you lazy good for nothing bastard. Come back with a real illness.
