“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A whale version has been printed on many images:
 
“Two whales walk into a bar. The first one says, ‘OUUHHHHWAHHHHHHH OUHHHHHHH AHHHH’ and the second one replies, ‘Shut up Steve, you’re drunk!’”
     
Versions of “Two whales walk into a bar” have been cited in print since at least 2004.

Two whales walk into a bar. One whale turns to the other one and says:
 
eeeeeeeeeuuuuuuuuuh ... UUUUUUUUH ... eeeeeeek (see, this is the part where you make whale sounds for about 15 minutes. Hopefully, some people start laughing at some point.)
 
The other whale turns to him and says, “George, what the hell are you doing?”
