Maybe not embarrassing, but I have the most of a bundle of JR Alts Cohibas that are too bad to smoke, but I can't make myself throw them away. I try one every 6 months or so (they are 3-4 yrs old by now) but they don't improve with age... :-D
I also have half a box of LaFinca robustos I can't throw away but not smoke either, they taste really bad, still grassy & bitter after 3 years...
Good thing (really a bad thing) here in Perth there is nobody smoking cigars, so I'll never have to show them to anyone..
