Olives or Grapes?

• Daddy got our salads ready to eat last night. He put kalamata olives on ours. 
• He got the boys some salad and then some grapes. He put one kalamata olive in with their grapes to get a reaction.
• Both boys love grapes and they eat salad pretty well to. We didn't think they'd like their one kalamata olive. 
• Mica was first. He was gobbling his grapes up, and wham got the kalamata olive in his mouth. He had a disgusted look on his face and said, "Man I thought this was a grape. I didn't ask for an olive!"
• Isaak was next. We were all watching him, knowing what was about to happen. He slipped the olive that looked like a grape into his mouth. Right away he had a look of disgust, and spit out the chunks of a half eaten olive. 
• I'm usually the prankster, so it sort of surprised me that Daddy pulled this prank.
