The Museum of Irish Heritage is where Peter Griffin takes Chris to find out his Irish roots in "Peter Griffin: Husband, Father...Brother?".

When Chris starts talking "street", Peter first thinks he is "speaking in tongues" and tries an exorcism. Later, at Cleveland's suggestion, Peter tries to get Chris to connect with his Irish ancestry at the Museum of Irish Heritage where they observe tableaus of Irish life and find that Ireland was a much more advanced civilization prior to the invention of whiskey.
