TheStreet's Jim Cramer is asked if he thinks Yahoo should buy Twitter with its Alibaba IPO windfall, but Cramer says Yelp is a better purchase. Cramer says the two companies already have a good relationship and Yahoo could get Yelp stock where it was before it sold off. Cramer also talks about the new WWE Network when he is asked if it is becoming the new Netflix. Cramer admits he missed a move in the stock but he wouldn't own WWE or Netflix shares. Finally, Cramer is asked what he thinks of Core Laboratories. The company recently lowered guidance and announced a conference call scheduled for May 12th. Cramer says the Permian has not been affected and investors should buy Pioneer, Cimarex, EOG Resources, and Anadarko.
