......with the help of KFC.
Actually found this out by trying to have some form of etiquette while eating at KFC.
Having gone there for lunch yesterday and having eaten said lunch I needed to break wind verbally but for once I didn't just burp out loud, instead I burped into my mouth filling it with air. Normally I would catch the burp in my hand and throw it in someones face (as you do) but trying to be polite etc I decided to hold it in my mouth and then proceeded to blow it down my straw into my 7UP, thus giving it a chicken-like flavour.
