We thank John Black for first drawing our attention to a pair of galaxies that only seemed inconspicious. We are very grateful to Martin Altmann for taking the H image at Hoher List and helping with its processing. We also gratefully acknowlegde the support of the staff of OVRO and OSO. The OVRO mm-array is supported in part by NSF grant AST 9314079 and the K.T. and E.L. Norris Foundation.
