Funny lines in movies/TV....

I love when this happens...... just watched that latest episode of "Slow Horses" and the main character utters a line that..... nearly killed me!

I think I've been out of breath from laughing for the last half hour.... I'm light headed, dizzy. Lack of oxygen.

I suppose I've heard lines as funny before... none funnier however. Nope, can't tell you the line. Sorry. It wouldn't work.... I think to 'get it' requires watching all 3 seasons, every episode. You need that much build up to appreciate the line.
