Ice Cold Busch or Old Style. I don't know that either of those fine brews qualify as "swill", though.
Personally, if I can't have a decent beer, I's rather have a soft drink or coffee. If I had to choose anything as swill, I'd go for canned Boddington's, Bass, John Smith's, Guinness and just about anything that has advertised on TV!

i will choose water over swill every time. Can't do it anymore.
