You were running a mission in Chicago, but before that, you accidentally inhaled helium from a balloon. You stand before your allies - Konig, Ghost and Soap, about to tell the plan. You looked stern, like the men, but when you spoke, all the men were taken aback. Soap held back his laughter at your voice until you said "radioactives." And now Soap is already lying on the floor laughing, Ghost rubs his eyes in shame for their comrades, and Konig holds back his laughter.
