The douche singing is Tim Hawkins. He is a "Christian Comedian" (I guess that means he cant tell poop jokes or whatever). If you look up his stuff you see how unfunny he is.
Also, this video was uploaded in 2010 before the whole chick-fil-a hates the gays incident.
Oscar Wildcat What's with the "not funny" tag? How is an ode to a shitty fast food franchise set to "God Bless The USA" sung by some poor mook in a flannel shirt not funny? The crowd response is just icing on that cake.
Ghoul The "God Bless the USA" parody is about 28 years out of date.
RockBolt Chick-fil-a has been overtly christian and has donated money to anti-gay groups for years though
Oscar Wildcat @Ghoul : Yes, but 28 years ago it would be a parody. Modernity brings us the sincere version to laff @.
