Adam Martoni
Adam Martoni was a cadet who attended Starfleet Academy in 2367. He enjoyed playing practical jokes on other cadets. 

During Wesley Crusher's first week at the Academy, Martoni reprogrammed Crusher's sonic shower to cover him with mud. Crusher managed to "get back at" Martoni when he reprogrammed an antimatter regulator in the physics lab to spray him with chili sauce. ()
