Harriet is the room-mate of Yelling Bird. Her nick-name, Sweet-Tits, was her only known name for a long time as Yelling Bird only refers to her as this. Because of this others, such as Andy and Randy, are [currently] unaware of her real name.
She is quick to anger when provoked, which happens a lot. Her filthy tongue almost rivals that of Yelling Bird.

- , where a girl similar to her is smoking a cigarette outside a store next to Coffee of Doom;
- The first panel of , though her hair color is darker; And again just a few strips later in .
- Possibly the clearest example is Steve and Marten walk past; and , where she apparently is in the background of the third panel while Marten is trying to resist moving too fast with Padma. This was also mentioned in Tumblr post QA Dump#22 by Jeph. , where she is sitting on some steps and reading a book about bird care (an oblique reference to Yelling Bird) while
- redraw of the (in which there is no bartender shown). , where she tends the bar. This is a
- The first panel of , again outside of Coffee of Doom.
In these strips it can also be seen that her eyes are a different color—blue instead of brown. In some of these strips, her hair color is slightly different as well.
