Many beers are sold in cans, though there is considerable variation in the proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing "skunked" beer) and have a seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic (PET) bottles are used by some breweries.

The mascot of Northwestern Athletics is Willie the Wildcat. The first mascot, however, was a live, caged bear cub from the Lincoln Park Zoo named Furpaw who was brought to the playing field on the day of a game to greet the fans. But after a losing season, the team, deciding that Furpaw was to blame for its misfortune, banished him from campus forever. Willie the Wildcat made his debut in 1933 first as a logo, and then in three dimensions in 1947, when members of the Alpha Delta fraternity dressed as wildcats during a Homecoming Parade. The Northwestern University Marching Band (NUMB) performs at all home football games and leads cheers in the student section and performs the Alma Mater at the end of the game.
