I know that many good ICO's around and some were very promising. HOwever, there are other ICO projects to which now looks like an April Fools who's team always talk to much but in the end of the ICO period all they have to do is to be silent, list the coin of the project and then dump the project. This is why we really monitoring from these guys to keep their promises before, during and after the ICO period.
Good timing with the name, so you saw april fools everywhere and you suddenly realized "wait a minute, some ICO's are so bad that they could literally be considered an april fools"? 
. That is really hilarious. I have seen some "joke" coins to be honest, https://uetoken.com look at this for example, dude literally created a joke token and told people "you are giving me money and that is it" and people literally gave him 50 thousand dollars for it, they didn't get anything back it was just pure fun and named "useless ethereum token" and people still funded him.So yeah, if you talk about these type of joke tokens they do exists and I find them amazingly fun to check, people who gave these guys money knew what they were doing, they didn't expected these coins to get high one day they literally just chucked and throw away their money to him so I see no problem with it.
