Elise, the Crying Sorority Girl, became famous for sobbing over a practical joke she played on her Alpha Chi sisters. Tonight, she explained on Tosh.0's Web Redemption she only used the now-famous fire extinguisher because she wanted it to snow.
Sorority Girl's subsequent punishment was that she had to clean the the Alpha Chi kitchen for an entire semester. Tosh suggested that—instead of returning to Alpha Chi—Elise pledge his sorority, Tri-Tosh.0Mega.
Tosh abused the Greek system and explained his group's hazing rituals before he offered Elise the spot, but—in the end—he made her dreams of magical fake snow come true.
