♪ ♪ that's weird al's eat it for you. appropriate for the next segment. it deals with food. in this case, real food and fake food.

oil being labeled extra virgin that doesn't meet the standard. it's hard to tell just looking at the bottle. i recommend if you can buying at a store that actually lets you smell and taste the oil which some gourmet stores do. when you taste it and smell it, you can tell the difference. once you try good oil, you'll know what it tastes like. much different from your standard run of the mill. >> and what do you look for on the bottle? >> i would look for a pressed on or harvested on date. not a use by date. the use by date is irrelevant. you want it to have been pressed or harvested within six to nine months. only good olive oil will have that on the label. >> parmesan cheese is another one. >> most people can't tell the difference. real parmesan cheese from italy is pure with no drugs. one of the most natural chees
