It’s 11 in 2011 -- 11 sets of twins, that is.
That's right, 11 sets of twins are preparing to graduate from William Tennent High School in Warminster, Pa. And while that number may seem high, it's not quite high enough to break a Guinness World Record for most twins graduated in one class.
In 2009, the Boston Globe reported 13 sets of twins graduated from Connecticut's Pomperaug High School.
Three more sets and they could have beat Pomperaug High!
William Tennet High School officials tell NBC Philadelphia that the twins will graduate on Friday, June 17.
