Headscratchers / What's with Andy?

• A lyric in the theme song is "Everybody knows me". Why does everybody know Andy?
  • With how many pranks he pulls (not to mention that some of them affect the whole town), NOT knowing Andy would be kind of hard, even if he is known to the populace as 'just a prankster'.
• In "Busting", Andy went through a Potty Emergency directly after drinking a jug of grape juice and thinks the grape juice is what is causing it. Doesn't it take a while before it reaches the bladder?
  • 1) Cartoon - logic takes a break; 2) Weren't those things big? If I drank a 2 litre bottle, I'd probably need to go too.
• Why did they change Lori's birthday in season two? In season one her birthday was on April 1st. However, in the horoscope episode in season two, she's revealed to be a Scorpio. If her birthday is on April 1st, she cannot possibly be a Scorpio, even if one takes into account Ophiuchus (which most don't), since that would render her a Pisces. And it isn't Andy getting her horoscope wrong since she straight up says "How did you know I was a Scorpio?". I don't think it's her going along with Andy either because she probably would have said 'I'm an Aries' or 'I'm not a Scorpio'.
