How many did you get right out of 20?
1 - 5: Aw shucks. You'll do better next time. Now that you know the answers and all.
5 - 10: Not bad. You probably won't get an invite to their next birthday party, but close enough.
10 - 15: Wowee, look who knows their celebrities!
15 - 20: OK, did you actually go to all their birthday parties?
