the para-goggles, and the storage facility, with Ray's assistance. He was also aware of the risk of crossing the streams. He spent a lot of time focusing on the stability of the storage facility and was concerned about the possibilities of a P.K.E. surge of dangerous proportions. Egon was particularly critical of Walter Peck's actions, and his attitude that the Ghostbusters were responsible for the explosion of the containment unit that occurred when Peck ordered a utility worker to shut the unit down. After their encounter with Stay Puft, Egon suggested an atypical solution when he recommended blasting Gozer's dimensional portal while crossing the proton streams to reverse the particle flow and send Gozer back to its dimension. Egon once tried to drill a hole in his own head (a process known as trepanning), which he says "would have worked" if Peter had not stopped him. Ghostbusters II (1989) Due to the large amount of collateral damage the city of New York suffered from the battle with Gozer, the Ghostbusters were sued by nearly every county and city agency in New York. Additionally a judicial restraining order was enacted which barred the Ghostbusters from performing services as paranormal investigators and eliminators, effectively putting them out of business. Five years after the events of the first film Egon returned to teaching at Manhattan College, working at its Institute for Advanced Theoretical Research and was conducting experiments on human emotions, during which he invented the Giga Meter, a device similar to the PKE Meter designed to detect and measure psychomagnotheric energy in gigaelectron volts. A negative test involved keeping a couple with marriage problems locked in a room for hours and gradually raising the temperature. A positive test involved a girl in a room with dozens of stuffed animals and a puppy. He was the first person Dana Barrett contacted when her baby carriage took off by itself. Egon recommended bringing in Ray, and they both performed a physical exam on Dana's son Oscar. Egon, along with Peter and Ray were later arrested after digging a large hole under First Avenue as part of their paranormal investigations to help Dana. During the course of their trial they were found guilty of willful destruction of public property, fraud, violating their judicial restraining order, and malicious mischief by judge Stephen Wexler (whom Egon said was known as "The Hammer").
