1991 commercial looking for former Milli Vanilli fans to take part in a class action suit against the group.
From Wikipedia regarding lawsuits:
"After the details emerged, at least 26 different lawsuits were filed under various U.S. consumer fraud protection laws against Pilatus, Morvan and Arista Records. One such filing occurred on November 22, 1990 in Ohio, where lawyers there filed a class action lawsuit asking for refunds for at least 1,000 local citizens who had bought Girl You Know It's True. On August 12, 1991, a proposed settlement to a refund lawsuit in Chicago, Illinois was rejected. This settlement would have refunded buyers of a Milli Vanilli CD $3.00 (USD), a cassette or L.P. $2.00 (USD), and a single $1.00 (USD). However, the refunds would only be given for a future Arista release.On August 28, a new settlement was approved. The same pricing structure was approved, along with a $2.50 (USD) refund to be given for concerts. A proof of purchase or ticket stub was required to take advantage of the refunds. An estimated 10 million buyers were eligible to claim a refund. A deadline to claim refunds expired on March 8, 1992. To this day, some refunds were never claimed by owners of Milli Vanilli products."
