It’s a winter epidemic that spreads each year as soon as the thermostat dips, but this season, you can protect yourself from a scourge that fashionistas fear more than the flu: Ugg Boots.

Landline TV and Babelgum urge you to protect yourself from elephant feet in its PSA for a new vaccine called Uggcitrin. Symptoms: Wearing leggings as pants, holding oversize Starbucks cups to make your hands more petite. Even in 2009, Washington Post fashion writer Holly Thomas advised readers that “Uggs should be a last resort.” Temperatures are still mild. It’s not too late to take a stand.
