Yetis are happy but bigfoot............. Why do they put laugh tracks in the sitcoms ? Yetti researchers don´t understand . Examples : the son arrive home and say hello to parents ( laugh track ) , the parents say hello (laguh track ). Son says " Where are all the tutti fruttis oh rutties of planet earth?" (Laugh track ).Parents answer back " You are a lemonade "(Laugh track). yettis say that there is a laugh democracy where you can laugh to mucho bonito jokes like hahahahaha but they don´t understand hearing laughs when the joke is bad . Still they advice that if you go to the ballroom dancing please buy a top hat if you´re man and a bycicle if you´re a woman.
