It all depends on how tenaciously you work on your own tasks.
If you spend a lot of time helping other toons (especially in buildings and/or invasions) you will build up your gags early. Hence, you will see 60 laff toons with level 6 gags.
If the toon focuses on tasks (and chooses generic tasks), they can get to be a 100 laff toon and still not have any level 6 gags. I have toon who didn't get the storm until he was 87 laff - his only level 6 gag was the cake. He is now 97 and almost done with two more laff boost tasks. I fully expect that he will be 101 laff and still have only throw and squirt at level 6, with the other gags at level 5.
Now, if by ALL gag tracks you really mean *ALL* gag tracks (all seven), then what you saw was a Disney developer that works on the Toontown program and was using a special toon to test something on the production servers.
