David M Willis (born April 3, 1979) is an American web cartoonist currently living in Columbus, Ohio.

After Blank Label Comics was discontinued, he has continued his online presence at Shortpacked!,[5] which has archives back to January 2005.

On September 19, 2008, Willis proposed to his girlfriend of four years, Maggie Weidner, in that day's episode of Shortpacked!.

It concerned the adventures of the fictional alien-fighting organization SEMME, and in particular current and previous members of Squad 128.

is considered to have been on December 25, 1999, but the switch between the two was not instantaneous; science fiction elements had crept into the college environment of Roomies!

It's Walky was followed by Shortpacked!, which was part of the same continuity but with an entirely different focus: the daily lives of a toy store's employees, including (oddly) SEMME veterans Mike and Robin.

After putting an end to his successful webcomic It's Walky!, Willis decided to turn Shortpacked!, his autobiographical comic, into a new title.

[12] The parody of Funky Winkerbean showed Les Moore and his girlfriend Cayla Williams (the two got married in Willis' strip) having sex while a ghostly Lisa Moore (Les' late wife, who died in 2007 from cancer) watched over them in approval, and in another panel, the resulting baby, who looked like Lisa, was ghostly in appearance.

strip also appeared weekly on toynewsi.com, Toy News International's website, for 250 installments from August 20, 2006, until July 31, 2011.

On January 17, 2014, the series' ninth anniversary, Willis announced that he planned to conclude the Shortpacked!

Dumbing of Age is a daily webcomic by Willis about college life at Indiana University with themes involving drama or comedy, occasionally with a mixture of both.

[15][16] Unlike Willis' previous Walkyverse comics, the series lacks science-fiction elements and instead focuses on slice-of-life plots.

Willis has a "Buffer Watch" on the page, indicating that there are comics drawn and uploaded weeks, or often months, ahead of schedule.

Willis also offers a regularly updated set of pornographic comics involving the characters, published and sold on the separate website Slipshine.
