Get A Brian You Morans
This easter egg can be found in two locations both in Single Player and GTA: Online.
In two locations, one in the rural Blaine County and the other in the city of Los Santos you can find signs that read, “Get A Brian You Morans”.
These signs are satire of a similarly ironic sign held by a pro-war patriot outside a Boeing plant in St. Charles, Missouri during 2003. Though his sign simply read, “Get A Brain! Morans”. The irony is that “morans” is supposed to be spelt, “morons” which didn’t help his case much.
