I was thinking about all the teams I couldn't remember even if I tried forever, and I wondered if this changed from person to person. The worst offenders for me were:
Cyndi & Russell (TAR2): The only thing I can remember from them is that: a) they were pastors who thought that God would help them on the race and b) They picked up a clue from a RB in Thailand.
Cindy & Russel (TAR4): Who were these people? I can only remember them stepping onto a pitstop mat and getting eliminated.
David & Jeff: The team thought of when it comes to unmemorableness. I can only remember them completing the FF in Brisbane and waiting in Sydney for the flight that made them a day late.
But the ultimate unmemorable award goes to:
Katie & Rachel: After I watched TAR17 for the first time, I went back and looked at all the teams, and I could not remember ANYTHING about them. Everything drew a blank. I rewatched the season about 2 weeks ago and now can only remember them in a car and running to the Pitstop.
