Okay, here we have META-Fail
The comments on the following Failblog.org posting are full of a half-dozen different fails themselves. The Fail posting itself has three different fails in it all by itself. Can you catch them all? (Spoilers in white below link)
http://failblog.org/2008/11/12/purebred-fail/
1. The original question is asking how to get a purebred version of something that is by definition a mixed breed (Puggle) (Easy)
2. Poodle is misspelled as Poddle. (Easy)
3. A puggle is a mix of a Pug and a Beagle not a Pug and a Poodle (or Poddle) (Hard)
The afficionados of fail are perhaps trying to become experts through practice? (Again, see comments)
