In a large stovetop pot pour 3 gallons of water and the three beers. Add the celery salt, paprika, garlic salt, pepper, bay leaf, dry mustard, ginger and lemons and bring to a boil.
Drop in the potatoes and cook about 10 minutes. Add the corn to the pot of potatoes and cook about 5 more minutes. Next submerge the sausage in the pot and cook another 5 minutes. Lastly, drop in the shrimp and crawfish and cook for 3 to 4 minutes on rumbling boil until the shrimp have pink shells and the crawfish have red shells.
Drain the liquid and dump the contents of the pot on a large table covered with newsprint. Serve with drawn butter, cocktail sauce and horseradish and watch your friends gather around the table.
You will need a 7-gallon stockpot and a crab cracking tool.
