Yeah, kind of like how those groups in the 1970s and early 1980s would name themselves after some particular date of significance like "Black September", I figured that some American group would come along and be called "The April 19th group" or some variation of that.

April 19th Freedom Fighters
19th of April Terrorist Brigade
19th Death Brigade, April edition
April 19th Deathtrooper Dragoons.
Unit 419
4th Battalion 19th Marines
194th Truth Brigade
Revere 419
Revere 194
Remember the 19th,

April 15th - The busiest day for the IRS and the biggest payday of the year for the government.
April 19th - The scariest day of the year for the US government.
