My sister noticed that one of her beauty creams has acacia in it. That's cool. My fraternity gets around. ;)

As for phone numbers, it depends. I've been able to memorize serial numbers on money and credit card numbers and driver's license numbers by finding patterns. I do that for some phone numbers too, but I especially like it when the phone number offers a visual pattern on the keys. This is made far simpler by the fact that the keys are in a square (and then 0, of course), unlike the numbers at the top of your keyboard, which are in a single row.
