You know your joke is bad when....
- All the comments rated -2 or less are the ones that say they actually like it.
- There AREN'T any comments at all.
- People ask if you are boring in real life.
- It was so "not funny", that it was actually funny.
And last but not least
- There are absolutly NO duplicates of your joke because it was so bad.
(I wonder if I can say the same for this)
