I'm sure you're not the first one to say that joke or make a play on words between a 'nice chest' and an 'ice chest.
.
Lol that's why I posted here so it can be on the record :p.
Random share: I thought of the Samsung Group Play concept 3 years before it came out. I told people about it back then and they remembered.
Did the same with bitcoin when it was 3$. They thought I was crazy lol.
I'm sure most people have thought they've come up with a good or original joke at least once in their life only to find out that that's not the case
. I think if you write a joke and then you find out it's already been done before then you just need to try harder as it's obliviously not that original haha.
