I always wondered who cleans all the marker “art”/graffiti from those panels on Voyager.

“It would appear that someone drew what is commonly referred to as ‘cock & balls’ style of art on my long-range scanner console, again, perhaps in an attempt to achieve humour. I shall review the security logs and crew medical data to find whoever did this.”

“Acknowledged. And find out where are they getting whiteboard markets, it might be some unknown alien technology.”
