Is It Reese's or Ree-Sees?

Howard tried the Reese's Klondike Bar: "Oh my god. This is the greatest thing I've ever...you've gotta try this one. Wait till you taste the peanut butter. It's like a peanut M&M but frozen." Howard then tried the Caramel Pretzel Klondike Bar: "I could eat the whole thing in a minute. I wanna become fat so bad." Artie agreed: "These people are geniuses! This is extraordinary." Howard then laughed at Gary's mis-pronunciation of Reese's as "ree-sees," but Gary claimed it never happened. Fred quickly settled the argument with a clip of Gary saying "ree-sees."
