Keep warm in bed

1.Try dropping a lit cigarette into the duvet cover.I never said you’d still be alive
2.Wear most of your clothes  to bed and cover with  a cotton,wool or silk wrap if it will still go on  over all your other clothes
3 Take some animals to bed.I do not mean men or women.
4 Use a sleeping bag as well as a duvet.Not good for newly married couples.
5.Clean the bedroom before you go to bed.Activity makes you warmer.Then  you can enjoy being virtuous for once
6.Hats do make you warmer.Or how about a wig? Golders Green is ok for both
7.Try putting on a heater… hard for the British but not impossible
8 Get angry and have a row.May be  a mistake?
9 Emigrate
10 Be wicked and have two partners.Nowadays anything goes
11 Look at something rude like Marks and Spencers lingerie.That will warm you  up
