Emily and Mabel started out as a single panel gag strip by Mike Angelo called Funny Angles. While the strip didn't start out with any recurring characters, Angelo started featuring the twin older ladies Emily and Mabel more and more as the years went on, and eventually renamed the panel after them. The strip centered around the titular characters doing their best to woo various men, usually unsuccessfully. They are always shown together, and I'm not sure if it's ever made clear which is Emily and which is Mabel, but I guess it doesn't really make a difference.

Here we see Emily or Mabel on an impromptu date with a mall Santa. It's interesting to note that often in the strips there is only one man that's the object of the ladies' affection, which makes me wonder whether they just happen to go everywhere together, even dates, or if they are competing with each other for the same man, or if there's some kind of bigamy thing going on. I'm not sure. Hopefully Mabel or Emily also has a Santa at a different mall that she plans to visit at work later.
