Susan has been touched by Roger's affection for Abi and invites him over to the house in a fit of matchmaking. In a romantic mood Susan recites the poem Ben wrote for her when they first got together. However Roger recognises "Susan's Face as a real poem, by a real poet, called "Your Face". Susan is livid.
Meanwhile in another money-making scheme Nick has decided to become a "human lab rat" and take part in medical trials. Ben, although initially concerned, is pleased to find that Nick's current set of pills might cause short term memory loss and make Nick forget where he lives.
Susan has put Ben in the doghouse because of his poetical deceit. She now feels that their love has occurred "under false pretences". Susan says she will not forgive - nor sleep with - him again until he writes a poem from his heart.
Meanwhile the side effects of Nick's pills are kicking in and he's now got the memory span of a goldfish. Michael (calling himself Stefan) takes advantage and makes a mint by asking repeatedly for "that £5 you owe me".
The next morning Ben and Susan are irritable due to their enforced celibacy. While Nick, having wised up to Michael's scheming, has devised a plan to remember things. He writes important notes to himself on his body and carries around annotated poloroids, like in the film Memento.
Abi invites Ben to her poetry class to sharpen up his writing skills. While insulting his classmates' poems, Ben manages to impress the nutty Vanessa, a lady with a penchant for "cynical pigs". The next day Vanessa turns up at the surgery asking Ben for a teeth clean, but is clearly after quite a lot more.
Back at home Susan has moved an exercise bike into the bedroom to work out her sexual tension. When Ben finally arrives with his epic poem "Ode to my lady" Susan is keen to cut him short and get down to business. Ben however is put out. He has worked hard on his ode and insists she listen to the whole thing - all 30 odd stanzas. The exercise bike comes in handy after all.
