Life has limits

Subreddit names and user names are limited to 20 characters (OK, so for subs it's actually 21...) Submit subs that amusingly hit the limit (perhaps by leaving out a character), posts that try to link to a sub that is waaaaaaaaayyyyyyyyyy too long, or other examples of amusing character limits. Also, check out r/21CharactersAndNoMore, and r/21CharacterLimitation for other examples of subreddit limitations!
