Absolutely correct about the agave (the blue is the only variety allowed to be truly called a tequila) not being a cactus - it is a succulent (completely different)
Also true that worms are not put in real tequila - its a myth that was started back in the 1940s to play with people in the US that thought you had to get Cuervo to get real tequila - although its probably the worst tequila on the market. The Mezcal - which is the generic name for all tequilas and a bunch of others in the past - is now separated out since "distillers" started making versions for the people in the US that wanted "status" bottles - its all the same shit but nowadays they distill it a little different much as Rye and Scotch are distilled differently.
As far as 24k rings - I have worn one for over 35 years and I get it reshaped every year and polished to get the dings out - it cost $6k in 1969 and has a bunch of diamonds and sapphires set in the gold that fall out on a regular basis - but fortunately back then when you bought a ring they gave you a lifetime protection certificate that replaces anything forever - and they still back it 35 years later.
Wine glasses - well - it all depends on what type of wine it is - some require that the wine bouquet be released during the drinking by holding the glass on the bowl - while some sparkling wines work better by holding the stem with two fingers and your thumb to make sure you dont transmit too much heat to the wine to release the bubbles too fast - of course having been brought up before Boones Farm was invented - a gallon of Gallo Burgandy or Chianti hoisted over the shoulder with your finger throught the loop works just fine at lunchtime in high school - especially if the sugar cubes, purple haze or sunshine have started to wear off
