"Diamonds"

In their 10th episode, Matt and Kevin celebrate their first
Valentine's Day at the Barone house, an occasion that merits
their full and undivided attention. The holiday provides the MLR
crew with an opportunity to investigate several conspiracies,
including the occult ministry of Barry Bonds, the social
conditioning concealed within elementary school Valentine's
traditions, and the possible influence of reptilians on the
production of Everybody Loves Raymond.
