It’s been a while since the words “manic” and “merger” appeared in a Monday morning post, but today we’ve got just enough grist for the mill to put one together. (Click here for an example of, sigh, how things used to be.)

Merck/Schering Plough: At some point in the last 12 hours or so, pharma giants Merck and Schering-Plough hammered out a $41.1 billion deal, which will combine the two companies. The new entity will retain the Merck name. In explaining the timing, which followed by six weeks Pfizer’s purchase of Wyeth, BCG Partners’ David Buik said: “Of course when the market is in a mood of desolation, this is often the best time to effect a merger or acquisition.” Lawyering the deal for Merck: Fried Frank’s David Shine, Philip Richter, F. William Reindel and Damian Ridealgh. Lawyers from Wachtell, Lipton represented Schering-Plough. Click here for the companies’ joint press release.
