I've had a few nasties, for sure...Victor Sinclairs of course (I actually puked after that one), I had a Padilla once that tasted like soap and a Joya Del Jefe which was probably the second worse cigar I've ever had. But the worst, by far was a Montecristo that this guy gave me and told me was a Cuban. He was a nice guy and knew I was into cigars, but the minute he handed it to me I knew it wasn't a CC. For starters the band looked photocopied, the wrapper was grey, but he and I both lit up anyway. I've had bad cigars before, what's the worst that could happen? Well, you know that smell when something has been pissed on and it's like a few days later? That's what this tasted like. Pissed on cardboard. He looked so pleased though about his Cubans that I just had to keep smoking and hold on. I think I made it halfway before I made up an excuse to chuck it, but in every way, it was the worst cigar I've ever had.
