Bert is examining a cookie in his hand
Bert: "Mmmmmmm, mmmm"
Ernie: (barging in) "A cookie?! Oh boy a cookie! I love cookies and oh boy am I hungry!"
(He grabs Bert's hand and starts bringing the cookie to his mouth Bert angrily stops him)
Bert: "Ernie, ho-ho-ho-ho-ho-ho-HOLD IT!"
Ernie: (tries again) "But it's a cookie and I'm hungry and--"
Bert: (jerks away) "Ernie, this is MY cookie I've been saving it all day just for ME"
Ernie: "Oh but, Bert, you wouldn't share the cookie with your best friend?"
Bert: "Ernie, I've been saving it; this cookie is for ME"
Ernie: "Oh but Bert, if this were my cookie, I would share it with you"
Bert: (skeptical) "No you wouldn't"
(Bert starts to eat the cookie, Ernie stops him)
Ernie: "Oh but Bert, if this were my cookie, Bert if this were my cookie, I'd be glad to share it with you" (abruptly he snatches it away from Bert)
Bert: "Ernie!"
Ernie: "Just a minute, Bert, just a minute"
Bert: "Ernie, that's my cookie!"
Ernie: "Oh but Bert, if this were my cookie, I'd gladly share it with you Just ask me"
Bert: "Ernie, that's--"
Ernie: "No, just ask me"
Bert: "This is silly (forced) Ernie, would you share that cookie with me? Augh!"
Ernie: "Why I'd be glad to! (He breaks it in half, gives one piece to Bert and gobbles down the other half [Did he get lessons from Cookie Monster?) See, Bert? I told you I'd share the cookie with you Isn't that better?" (leaves)
Bert: (standing bewildered with the half-cookie) "I don't understand "
(Ernie pops back, asking): "Say Bert, would you share that half-cookie with me--"
Bert: "AAAAUUUUUGGGGHH! Leave me alone!"
