In order of importance

There are several holidays in the Month of May, some you might not be aware of.

May fourth. Happy star wars day! May the fourth be with you!

*Cough*

May fifth  Cinco de Mayo

May eighth  The one year anniversary since the Star trek movie came out!  *Cough, cough* Don't ask how I know that.

May ninth Mother's day! 

To celebrate all these wonderful holidays, I suggest you eat croissants with chocolate frosting.
It's good.
Trust me.
