Shameless Londonist Plug of the Day
It's Friday. Pub day. Hell, every day is pub day. Which is why you need to get the Londonist Guide to London Pub Crawls (optimistically subtitled 'volume 1'). Yours for Kindle and other devices for less than the price of a pint. Get it here.
Good Cause of the Day
Try a Musical Bingo night at the Bedford Tavern, in Balham, on 23 May, all in aid of the Royal National Institute of the Blind (RNIB). Prizes include a BMX, £100 of beauty vouchers, a photoshoot and prizes donated by local businesses. The game is just like regular bingo, but instead of shouting out numbers, songs will be played! A medley of tunes will be belted out while players simply mark them on their bingo cards accordingly. Tickets cost £7 for the game, which begins at 8pm, and is organised by the RNIB London and South East fundraising team. More information here.
While we're thinking of number games, let's play the Countdown numbers game but with a meteorological pop-culture twist. Hey, it's Friday.
Make today's maximum temperature of 17 degrees Celsius using only famous degrees...
Start with the six degrees of Kevin Bacon.
Multiply by the 1960's female vocal group The Three Degrees, to give 18 degrees.
Take away Banarama's Love in the First Degree.
Result, 17 degrees.
Now, your turn for the letters game. Rearrange the following to make the rest of the weather:
