This is how to respond to the joke.

:)

Neither, "were" implies past tense.......

Who "was" left, not who "is" left; at some point in the past, one guy was on the boat and the other guy was in the water. Next time, think carefully before posting an unwise comment.

You have no comeback. \:-)

Calm down there bacon bit's, you might choke on a lego.

This meme is original: It is a reply to another meme. Obviously there would be a connection between the two. I am very calm.
BTW, thank you for warning me that LEGOs are a choking hazard. I really appreciate your concern for my well-being. :)

BTW, just some friendly advice: When you're about to start arguing, take a minute to cool down. Then think of support for your stance; If you can't come up with much, don't start arguing because you are doomed to failure (if the other person is competent and has good backup). And don't resort to name-calling or insults: That will only prove you know your argument is weak. Have fun with life.

You must be responsible for the California flooding, with all those salty tears Mr. Bacon bits.

Rain is freshwater. Therefore, rain cannot be salty.

You just slapped yourself. You were the one to bring up flooding (which is [muddied] freshwater caused by rain) and tears. Congratulations! You have miserably failed at being an effective troll!
Don't cry; it's OK. Need a tissue? :J

No, but I have ADHDOS (attention deficit/hyper activity disorder on steroids).
