As bad as I hate to admit it, mine was this Smallmouth Buffalo Carp
Caught while Crappie fishin on an itty bitty minnow and light wire #6 hook. It was quite the battle getting this brute to the boat, had to chase him all over the lake before he would give up.
Not that prestigious of a fish... but he was Big, Mean, Ugly, and Nasty (the same way I like my wimmins!)
... not as big as the Buffalo, but this landlocked Striped Bass put a heckuva smile on my face too!
