Leo Gertsenshteyn reports:

A man in a banana costume just ran screaming through 209 Butler. Luckily, it has promptly returned to being an uneventful night of studying and NSA sex in the stacks.

And overheard in Butler Cafe:

Girl: Oh guess what! I’m soooo excited! I got my books on
Mesopotamia today!
Guy: Oh, cool. What class are they for?
Girl: Oh, they’re just fun books on Mesopotamia, for my own reading
Guy (a little caught off gaurd): Oh . . . I didn’t know they made
FUN books about Mesapotamia.
Girl: Don’t be silly! Are there any other kind!!??
