7/18/1515 should be GROO Day. The 7th letter of the alphabet is G, 18th=R, and OO=1515. I did a class about riddles recently and I used the Batman Forever movie Riddler riddles in which he uses numbers to make Mr. E for Mr. Enigma. April Fools is tomorrow and that would be an ideal day as well. Hoppy Easter! Grooly, Eli Stamp
