I don't think I've laughed harder than when the Tiger shark started singing.
Loved that one, had me in stitches. Also great:
Quint's introduction about his lost rollo
"Hunter S. Thompson goes fishing."
"It's Charley the Tuna, I know it. Last time I was only able to hook him through the beret."
"Huh, music got all whimsical all of a sudden."
"He went under with three barrels. Quint's belief system is shaken to it's very core."
The facial hair/head hair combo awards bit
"Oh yeah!!"
"There's me spleen."
And so many more, loved this riff (except maybe the Sherman's Lagoon crack, me being a SL fanboy

)
