Little people are not objects to be greased up and hurled down a bowling lane just for the purpose of the audience enjoyment — this according to the Little People of America, which told media outlet TMZ that the “midget bowling” of Zac Brown is a “direct insult” to little people everywhere.

According to previous reports, TMZ posted a footage of country singer Zac Brown going “midget bowling” last weekend at a motorcycle rally held at South Dakota — where he slid a little person named Short Sleeve Sampson down a greasy bowling ramp and into bowling pins.

However, a rep for Little People of America — United States biggest non-profit organization for people with dwarfism — told TMZ, “Little People does not endorse any activity in which a person of short stature is used as an object rather than regarded as a competitor, in a ‘sporting event.’”

“We believe that such practices are a direct insult to the equality of people with dwarfism, grounded in a respect for basic human dignity,” the rep added.

Meanwhile, Short Sleeve Sampson placed a call to TMZ Live earlier this week, insisting that there’s nothing wrong with a little “midget bowling” every now and then.

LPA is an organization that provides support, resources and information to individuals with dwarfism as well as their families. Membership in LPA is limited to people 4′ 10″ and under, or those with a diagnosed form of dwarfism, their families, or those who “demonstrate a well-founded interest in issues relating to dwarfism.”
