From wikipedia:
In the final vignette Eric
Young arrived and, after Young knocked
over a glass, Shark Boy woke up and did a Stone
Cold Steve Austin impression, telling everyone to leave
and stating "and that's the bottom line 'cause Shark Boy said
so!"
On the January 24th episode of Impact, Shark Boy was "reborn" as
"Stone Cold" Shark Boy,making the crowd say "what" and using these
catchphrases:
Shark Boy also signed off with Austin's signature of pouring a
liquid ("Clam Juice") over his face and giving the audience the
"middle finger salute" from the top ropes. His new entrance music
& video are similar to Austins showing a shark instead of a
rattle snake. It was announced that the parody of Steve
Austin would only continue via the fans's
response.
Steve Austin
said "only a cheap, second rate company like TNA would do something
like this anyway".
