Solve this Riddle if you can

It means the sign maker is an alcoholic and the person who bought the sign will be searching for someone else to do it in the future.

Is the old man with a cat right?

 i like true false games  here is an example

1. my uncle flew a plane which crashed in the Bermuda Triangle

2. my son, age 16, lifted 170 pound barbell above his head.

 Which statement or statements are true?

@ponz111: both statements might be true or not. How can I know?

The first sentence is ambigious to me. It might say 'I have an uncle that once flew a plane that later crashed in the Bermuda Triangle' or it could be that your uncle was flying it on that fatal flight. I don't have a clue which version is more likelty to be true, hence I do not know if one of them is true.

The second sentence is something that describes what I have done on my sixteenth. So I know by experience that it is possible. I don't know if it is ok to say a 170 barbell, but I interpret it as a shortcut expression. That is allowed in Dutch. Furthermore can he have used some devices to help him lifting the barbell. Ambigious again. True or false? Who knows?

First one is a lie. If it was true, you'd say vanished in the Bermuda triangle, not crashed. How would you know it crashed? Second one is true cos it's not weird enough to be a lie.

The first statement is true and the 2nd statement is false.

i have lifted a 170 pound barbell above my head [clean and jerk] but my son never has. We do not any longer have my old set of weights.

My uncle did fly a plane which crashed in the Bermuda Triangle. He escaped alive.

That same uncle used to jump off platforms more than 30 feet high.

He did this at least 50 times and survived. 

True false statements are a game of logic, not of knowledge.

Are the next two statements true or false:

1. False implies true.

2. The next two sentences are equal:

a. If I see a bat, then I see a mammal.

b. I see a mammal or not a bat.

deep is obviously the answer
