Trivia

 * According to the coroner, aneurysms are the number one cause of death for party performers. This is not the first time a party performer has died of an aneurysm on iCarly.
 * Joey Rich, who portrays Albert, hit his head pretty hard on the table during shooting.
 * There were several takes of the scene where Albert's letter explodes. In the first take, the explosion was huge. The heat was intense and it blinded Joey Rich for several seconds. He got scared and jumped Miranda and Jerry's lines. Director Anthony Rich noticed that it was too big and had the exploding paper cut down in size. Writer Kate Stayman-London came up with the Latin spell that Albert, Carly and Spencer say. "Mysterium Casu Interficere" translates to “Kill the mystic.“
