A number of years there was a boy who was thrown out of his Yeshiva. So he went to his Rebbe the Beis Yisrael of Ger who suggested that he go to the Amshinover yeshiva whose Rosh Yeishva was Rav Chaim Milikovsky ztz"l [who was a tremendous talmid chochom who had learned in the Mir in Europe], the son-in-law of the Amshinover Rebbe's Reb Meir'l ztz"l.
One day the Rosh Yeshiva called him in and told him he was expelled from the yeshiva because two trustworthy witnesses came forward and said that he had been out drinking on Saturday night. The boy protested that he actually been at the melave malka of the Tolna Rebbe in Beit HaKerem [where he lived at the time]. The Rosh Yeshiva didn't believe the boy. But the boy insisted he was telling the truth and suggested that the Rosh Yeshiva call the Tolna Rebbe to ask him if the boy was really there. The Rosh Yeshiva said that it won't help. The Tolna Rebbe would swear falsely on a sefer torah to save a Jew, so of course he'll defend the boy.
The boy ended up leaving and going to the army. Some time later the Amshinover Rebbe R' Meir'l was feeling really guilty about the whole thing. Maybe he had told the truth after all. So he contacted the Tolna Rebbe to ask him whereupon he said "Of course he was with me and I'm willing to swear on a sefer torah to prove it..."
Reb Meir'l actually believed him and in order to appease the boy he gave him a special chavrusa - his grandson and present Amshinover Rebbe Shlita. They learned together for two years.
