Many comparisons have been made between "How I Met Your Mother" and "Friends". The realtor (Maggie Wheeler) in this episode played Janice in "Friends", a reoccurring character known for her annoying voice. Phill Lewis, who played the loan officer, played Chandler's advertising boss, Steve, in 3 episodes of "Friends".
Phill Lewis, who plays the Loan Officer, previously starred on the television series "The Suite Life of Zack and Cody" (2005). His character was named Mr. Moseby.
When the champagne is opened, the same sound effect of the cork popping accompanied by Lily's scream is used as in the earlier episode where Marshall gives Lily a black eye in the kitchen on the day they got engaged to be married.
Phill Lewis also guest starred on an episode of Buffy the Vampire Slayer with Alyson Hannigan.
