MANHATTAN, Kan. — Kansas State University is apologizing for their band’s halftime performance during their season opener Saturday night.

The Kansas State band made a formation depicting the Starship Enterprise from “Star Trek” attacking a giant Kansas Jayhawk during their game against South Dakota. The Jayhawks are the Kansas State Wildcat’s biggest rival.

At one point, the Enterprise heads toward the Jayhawk and that’s where some viewers thought they saw something else — male genitalia.

Uh… interesting formation for the Kansas State band. pic.twitter.com/SB36JBFEEc — Timothy Burke (@bubbaprog) September 6, 2015

The band director and the president of the university later apologized.

I am sorry if anyone was offended by the performance at half-time. https://t.co/5589bLIJRs — Kirk H. Schulz (@kstate_pres) September 6, 2015

We apologize for anyone offended by our halftime performance depicting the starship enterprise and the Jayhawk mascot. — KState Marching Band (@KStatePride) September 6, 2015

Kansas State Marching Band Director Frank Tracz released a statement saying the band’s set formation was not meant to be “anything other than the Enterprise and the Jayhawk in battle.”
