Originally Jenny and Mandy were sisters in the Theta Alpha Theta Sorority, which owned the Haus for sometime up until 1993. Presumably they both passed away in a tragic accident during a rush event, which caused the Haus to be abandoned and it stood empty for a decade until it was purchased by the Samwell Men's Hockey Team in 2003.
Jenny and Mandy are particularly fond of Ransom, and have a habit of tormenting him in various ways. Some of their typical antics include:
- Displacing Ransom's things, such as his jock strap the day before a game
- Giggling in Ransom's presence
- Disturbing Ransom in the bathroom
- Touching Ransom's butt
- Playing 90s hits, such as 'Oops!... I Did It Again' by Britney Spears and/or the Samwell Fight Song
- Creating cold spots that only Ransom seems to detect
