SAL 3000 was Third Street's new clock and bell system installed in "Schoolworld" because Spinelli broke the original clock. Originally SAL 3000 was a friend to the students. But once Gretchen said technology was man's best friend he said "Thank you Student Gr-gr-Grundler," showing the first sign of malfunction. Once SAL 3000 was shut down Prickly said he wanted the new SAL 4000 when it came out in 18 months. In the episode " The Terrifying Tales of Recess," it is revealed that Third Street got the new SAL 4000 upgrade. SAL turned evil after his first malfunction.
