The Geoff Johns "smile panel." In which a character responds by smiling and saying (generally) a one word response.

Artists who can't get their work out on time. I like Hitch's work, but 2-4 months is a little silly. Especially since Ed Bagley does great work on Ultimate Spider-man and those issues are sometimes bi-weekly.

Only 5 years after ending crossovers because people complained about them taking over titles for a month, DC does a stryline that takes over every title for a year and involves six 4 issuemini-series and a 52 issue series that needs to be read to understand what's going on in current titles.

Bow ties are coool.
