Headed to a game? Might want to check the sponsors before you dress for the event. More than 1,000 Dutch soccer fans probably wished they did as they sat in their underwear watching their national team play in a recent World Cup match in Stuttgart, Germany.

The fans, decked out in orange pants complete with fuzzy lions' tails (in honor of their Dutch mascot), were given a choice at the stadium gates: Drop the lederhosen, or skip the game.

So they dropped.

It seems the aforementioned pants are trademarked garb of the Bavaria Beer Company, and thus forbidden en masse at the World Cup games, which are exclusively sponsored by Budweiser.

In an NPR interview, Robert Siegel spoke with Bavaria Beer Chairman Peer Swinkles about the mandatory disrobing, during which Swinkles brought up an interesting point: Would fans also be forced to remove Nike shoes for fear of a mass ad for a competitor of World Cup sponsor Adidas?

Makes you wonder... Also makes you wonder what would've happened if any of the Dutch fans happened to be wearing Heineken underwear. Maybe Budweiser is just trying to find a market for Budweiser Speedos.
