As faithful Nonsense NYC subscribers, we’ve been clued into everything from condiment wars to absinthe parties (mmm, absinthe), but we’ve never seen (or smelled) anything quite like the Chinatown Garbage Tour. Tonight at 9 p.m., Brooklyn-based artist and rogue taxidermist Nate Hill will share wisdom gleaned from his weekly searches for animal parts (he incorporates them into his YouTube show “Chop Chop” and his Dead Animal Man project — which you probably don’t want to know about). A test run of the tour, for friends, yielded precious bounty: “We found some frog’s heads,” Hill remembers. “I’ve found small sharks a foot or two long. Usually you’re overrun with fish guts or tails, so when you find something like a shark, it’s really special.”
