@MrsMoastyToasty and @TheNationsFavourite there aren't enough Fast Show references on here! I think that was the best show ever for catchphrases...
ooh, lovely old tree...lovely old wall...(when driving with the kids)
scorchio! and cumulonimboos when it's cloudy (every morning at the window looking at the weather)
this week we will be mostly eating..(usually said whenever anyone asks me what's for dinner)
very, very drunk (I actually know someone who talks exactly like Rowley Birkin QC in real life and I find it absolutely impossible not to say "were you very very drunk?" every time I see him!)
anyone fancy a pint? in awkward situations
Harry Enfield too - "considerably richer than yow" whenever a flashy car goes by and "women! know your limits!" whenever a female friend has a significant achievement, most recently when a friend got promoted!
