LOL. I had three graduate students (PHd CompSci candidates) working for me back at UMass. I come around the corner to see them all clustered around one of the PCs. Apparently one of the graduate students had slid a CD-ROM between two of the blanking panels instead of opening the CD-ROM tray. They were trying to figure out where the CD had gone.

After a chuckle, I showed them how to open the case and retrieve the CD.
