"The Mason Twins" marks the second sale this development season for the writing partners.

NBC is getting into the Casey Wilson and June Diane Raphael business.

The network has given a script order to The Mason Twins, a comedy from Raphael and Wilson, The Hollywood Reporter has learned.

The comedy centers on fraternal twins in their 30s who find themselves living under the same roof and not at all where they thought they'd be.

NTSF's Raphael and Happy Endings' Wilson will pen the script and executive produce the ABC Studios half-hour alongside Stacy Traub (Glee).

Mason Twins marks the second sale this development season for ABC Studios-based Wilson and Raphael. The writing duo -- along with Happy Endings co-showrunner Jonathan Groff -- received a pilot production commitment from ABC for half-hour pitch DINKS (aka Double Income, No Kids). Raphael and Wilson will pen that script as well as executive produce via their overall deal with ABC Studios.

Mason Twins and DINKS are the latest collaborations for Wilson and Raphael, who wrote the feature film Bride Wars and wrote and starred in Sundance's Ass Backwards (the latter will be released theatrically Nov. 8).

Wilson and Raphael, who met at New York University and went on to perform together at the Upright Citizens Brigade, previously teamed to develop comedies Walk of Shame and The Housewife at ABC with Sony Pictures Television for the 2011-12 development season.

Shapiro, she most recently starred in ABC's comedy pilot Pulling and next will guest-star on NBC's Parks and Recreation.

Wilson is with UTA, Odenkirk Provissiero Entertainment and Shapiro.
