Remember yesterday on MAD MONEY? Jim Cramer said he would give us a pick a day for companies Yahoo! Inc. (NASDAQ:YHOO) could buy in order to "save" the company from the havoc wrecked by CEO Terry Semel. Yesterday's pick was Bankrate, Inc. (NASDAQ:RATE), and today he proposed Yahoo! buy The Knot, Inc. (NASDAQ:KNOT).Why The Knot? Cramer says it is the premeire wedding destination online. In fact, whether or not his matchmaking is successful, he thinks The Knot is a good investment. He thinks that the street is worried that KNOT may be too expensive, but he is wrong. He thinks the stock is going higher. Say it, and it's so. The stock closed at $23.93 today, up over 2%, but was up as high as $24.84 in after-hours trading thanks to Cramer's romancing.
