If it's onscreen, it's canon...right?

If that is the case, the commercials would be canon, too.

this too? an away team trapped on earth? Night Court - Old Vs. New Star Trek - YouTube

Night Court was such a great show and I thought I had seen every episode but I definitely missed that! Thanks for sharing it, @JohnDW

[The_Gorn_Abides]

Definitely Canon.
