Television Review – The Big Bang Theory – The Expedition Approximation
Sheldon and Raj decide to move into one of the university’s maintenance tunnels for a week to simulate black-matter physics experiments being conducted in deep hot mine shafts. They seem to be coping OK until Sheldon discovers rats in the corridor.
Leonard and Penny fall out over money when Penny tries paying Leonard back money he gave her as a gift at a time when she needed it. The engaged couple rashly seek advice from Howard & Bernadette only to find their married friends have the same problems only worse.
A contrived episode spoilt by the closing lines being used in the frequently repeated trailer but the Penny / Leonard story arc works well enough.
