Suspicious of Whistlers is Washington University in St. Louis' premier long form improv team. The Whistlers perform regularly around campus and in the St. Louis area. "Never the same, always insane."
The Whistlers perform primarily Harolds, La Rondes, and Monoscenes, but dabble in other forms. These have included Bat, Musical Improv, Armando, and original formats. The Whistlers have performed at NCCAF twice, and have travelled to Chicago as well.
