Actress Madhuri Dixit-Nene took fans down memory lane on Monday by first enacting as Nisha from "Hum Aapke Hain Koun..!" and then taking up the #GulelChallenge on the film's 25th anniversary. One of the iconic scenes of the 1994 film was one where Madhuri's co-star Salman Khan playfully takes aim and shoots at her derriere using a catapult.
