Turns out that grilled-cheese-sandwich lovers are having way more fun in the bedroom, with 32% having sex more than six times a month, compared with just 27% of people who don’t like the sandwich. Also, 73% of those who like the sandwich said they had sex at least once each month, compared with the 63% of those who say they don’t like the snack.

That might be because 84% of grilled-cheese-sandwich lovers are more adventurous and likely to travel, vs. 78% of nonlovers. Or it could be because the grilled cheesers are more charitable (81% vs. 66%).

If you’re skeptical, well, remember that Skout’s interest in grilled cheese is for a good cause. The site will donate to food banks in San Francisco and Marin County to help feed hungry kids every time users give a “grilled-cheese gift” to someone else on the site.
