Had to put this one up, even though it is not very appropriate:)
OT: "J, are you ready to go to exercises."
J: "I think so." (stands still)
OT: "So, let's go. We are going to be late"
J: (stands still)
OT: J, come on please!
J: (gives a looooooong, very loud fart; is startled by the sound he makes and then says) "I just farted?"
OT: "Yes J, you did."
J: (laughing) "Well, well well..."
OT: "Okay, let's go. Are we taking the scenic route, or are we going to go in the elevator?"
J: "Let's go in the elevator"
OT: "As long as you don't fart" (smiling)
J: (looking quite serious) "I never fart more than once a day."
