- 30th anniversary of the theatrical release of Star Wars
- Opening night of "Pirates of the Caribbean: At Worlds End"
- Towel Day, in honour of Douglas Adams.
Set two weeks after his death, Towel Day is intended to be a wake in honour of the memory of Science Fiction author Douglas Adams, and his contribution to the geek canon with the increasingly inaccurately named Hitchhiker's Guide to the Galaxy Trilogy. To mark Towel Day, one shows how much of a hoopy frood one is by proudly displaying a towel all day.
So if at the end of May you see someone in a feathered tricorne hat, polishing a lightsaber with a nice mauve towel, you will know the reason why.
