Imitation

A guy walks into a bar and sits down on the barstool. "Hey, barthendther, gifth me a beer." The bartender walks over with a tall cool one. "Here'sth your beer."
The other guy sits up straight. "Heey, you're imithating mee."
"No, I talk thith way too."
"Okay, I guesth itth okay."
Later, a big burly guy walks in and sits down at the other end of the bar. "Yo, bartender. Gimme a beer." The bartender responds, "One beer comin' up man."
The little guy gets ticked off and yells,"Heey, you were imithathing mee!" The bartender comes over close and replies, "No, I wasth imithathing the other guy."
