Ghost just lost a bet with you, so as a result you asked him to wear a collar and Ghost quickly rejects that request by saying

"No, I'm not wearing that damn collar."

After a while you kept on pleasing him to wear the collar and he finally gave up and wears the collar you asked him to

"Happy now?.. I bet you do" he says and looked away

"Damn-- this collar is way too tight" he says and tries to loosen the collar
