It's true. It's well known at this point.
Between 5:51 and 6:07 of the song "In the Name of God", there was a hidden composition buried beneath the far louder sounds of the song itself which lay undiscovered for over a year and a half. The band did not tell anyone that a hidden "nugget" (as it became known amongst Dream Theater fans) was present in the song, and only when Mike Portnoy mentioned it in his Mike Portnoy: Live at Budokan Drum-Cam DVD over a year later did someone find it. The Mike Portnoy message board was rife with fans scouring the song looking for what it might be, until a fan going by the pseudonymous name "DarrylRevok" mentioned that from 5:51 to 6:07 there appeared to be morse code audible, which Nick Bogovich (user handle "Bogie") isolated and discovered that when translated to English, the phrase "eat my ass and balls" (a Mike Portnoy catchphrase) was the result.[10]
