You know that Pseudacorus is NOT what you and your lawyer do when you don't like the music!
You name your new seedlings for your cats. Or, if you name your new cats after your irises.
You let your dawgs do the digging for your next iris bed. If you don't have dawgs, you might still be infected if you plant your new iris beds inside old truck tires in the middle of your yard because you're running out of space.
The flags in your front yard all have petals...
You're pregnant, but you spend more time thinking of names for your new iris seedlings than you do for your new baby.
You smell grape Kool-Aid and immediately think, "Iris pallida!"
Your bathroom reading material is the latest Schreiner's catalog.
Any other symptoms?
