what's the WORST cigar you've smoked?

The strangest thing happened the other day, the worst cigar I've had changed from the CAO America to an Oliva Serie V belicoso o_o it was so bad, i couldn't finish it, and the flavors were indescribably bad, but i have had the robustos frequently in the past and loved them, i wonder if it was the way it was stored in the b&m's humidor, but i was sick after 3" of that cigar
