When you're as immature as we are, the short list of high comedy includes such classics as people falling down, farting and, of course, suggestive names like "Ben Dover" or "Seymour Butts."

So we are unamused by a study that says funny surnames like Cockshott, Balls and Shufflebottom are on the decline in the U.K., dropping by up to 75 percent in the last century as people either refuse to pass them on to their children or emigrate entirely (presumably in shame).

The study found that the number of people with the name Cock withered from 785 last year from 3,211 in 1881, those called Balls fell to 1,299 from 2,904. Also significantly decreased were slightly less dirty but still very silly names such as Smellie, Gotobed, Shufflebottom and Cockshott.

Luckily, the surname "Wang" is still experiencing significant growth. (Could. Not. Resist.)

The only thing more awkward than those names are these signs.
