Ilana gets the nickname "Other Tonya" after Marcel refers to her as "a real Tonya Harding" for tripping a coworker. In S3 E3 Game Over, Abbi mentions she was over competitive in highschool and given the nickname "Tonya Harding"
When Ilana is exclaiming she made $800 in tips, Marcel (RuPaul) tells her "condragulations." This is a subtle nod to the fact that RuPaul is one of the most legendary drag queens in history.
