rubber penii
Written on a white sticker and stuck on the front of drawers and filing cabinets in school. I think it was started by one of the German exchange students, but it carried on appearing for about a year. That's it. Simple but perfectly funny. I always liked the charming spelling.

Was that supposed to be a sophisticated spelling of what would today be written as "rubber penises"?
Surely that would only work as the plural ending if it was spelt "penus"? Look at examples:
Radius - radii
Octopus - octopi
Think about it...
