Shenanigans! 

Used as an interjection, "Shenanigans!" denotes a person or event suspect of unscrupulous or dishonest conduct. If one believes they bear witness to such an occurrence, they should immediately call "shenanigans!" to draw attention to it.

There's no way he could have done that by himself...I call shenanigans!
