Would you want to drink something that reminds you of skunk juice? Yes, beer CAN smell bad, hence the term "skunky" beer. It occurs when beer is exposed to UV sources, such as the sun and, believe it or not, flourescent lights. Regular incandescent lights don't cause this reaction.
There's a reason why so many breweries bottle in the dark brown, UV filtering bottles, after all.
