By allowing the lightcones to tip over according to the conservation laws of an one-kink in static, Schwarzschild metric, we show that there also exists an instanton which represents production of pairs of chargeless, nonrotating black holes with mass M, joined on an interior surface beyond the horizon ar r=M. Evaluation of the thermal properties of each of the black hole in a pair leads one to check that each black hole is exactly the antiblack hole to the other black hole in the pair. The instantonic action has been calculated and seen to be smaller than that corresponding to pair production by factors that associate with the Bekenstein-Hawking entropy and a baby universe entropy 2pi2M2. This suggests these entropies to count numbers of internal states.
