Only fools and horses. When Rodney goes to the auction and buys a boatload of suntan lotion - in the middle of winter. The writing for the first 10 minutes of that episode is comedy genius.
Does not matter how many times i watch it, it always cracks me up.
Del Boy: [after seeing what Rodney had bought with the company money]
Whats the weather like out?
Uncle Albert: Its parky, Del!
Del Boy: [sarcastic] Good, good! Nice thick frost is there?
Uncle Albert: Bit slippery underfoot, yeah!
Del Boy: Oh, cushty! Nice notherly wind howling in from the Urals is
there?
Uncle Albert: Cuts right through you, Del!
Del Boy: Lovely! Because today, Uncle Albert, owing to young Rodneys
foresight and GCEs, while all them other plonkers down the market
are selling woolly hats and thermal under-wear, were gonna make a
right killing. Do you know why were gonna make a right killing? We
aint got woolly underwear! [produces bottle from box] *Weve* got
sun-tan lotion! And we aint got just a little drop of sun-tan
lotion! Weve got 500 bloody quids worth of the stuff!
Rodney: Ive told you, I bought it as an investment!
Del Boy: An Investment! Menage a trois! In the middle of the worst
winter for 2 million years, with the weatherman laying odds on a
new Ice Age - this dipstick goes out and buys out Amber Solaire!
