It’s called “the things you can’t Un-See,” an Internet phenomenon where a buddy sends you a non-descriptive link with some bland come-hither line like, “I thought you would like this…”

Clicking it results in an involuntary gag, or a spouse that thinks she’s married a pervert – now you’re obliged to find something equally gross to return the compliment to this erstwhile friend.

The link I clicked was not so innocent, entitled “The 10 Nastiest Fish in the World,” – and the result would send a hardened Brownliner fleeing in terror. A better descriptor would be “The 10 Fish you’d cut the fly line to Avoid” – featuring lots of teeth, slime, and the urge to go vegetarian.

Fly fishing for the above Goliath Tigerfish is billed as “one of the last frontiers” by the folks at North Wales Flyfishing School, 9-11 weight, with 40lb single trace wire leader required. It looks more like suicide to me, I’d be lucky if I could summon the nerve to stick my toe in the river.
