I've worked backstage in theatres for over 20 years now. Yes, those bring back memories of sending out newbies for things like -

A spool of shoreline (For the HMS Pinafore and Mr. Roberts)

The left-handed hammer (when you are a lefty and a right-handed hammer makes you miss because it's weighted wrong.)

The metric Crescent wrench (For those metric nuts and bolts that pop up more often now.)

The table saw silencer (when the saw is too loud during rehearsal)

A skyhook (to lift things, of course)

Dark lightbulbs (when the regular ones are too bright)

Plaid/Striped paint (How else are you going to paint it that way?)

The paint separator (To get back all the pigments you mixed in when you're done with that color. It works kind of like a cream separator.)

The sand dryer (It's used to dry the wet sand in front of the outdoor stage. In a pinch, there's a big yellow one up in the sky that can be used.)
