Not Going Out (2006)

S15E03 Superfan

Lee gets a Cameo birthday shout-out from Nigel Planer, one of his comedy idols, and has no clue that Lucy was the one who paid for it. Later, spotting Nigel in a crowded restaurant, Lee hurries over to say hello, convinced they're practically best mates now. Nigel, needless to say, has no idea who he is.
