Remember, remember the 5th of Nov, be safe tonight guys

Oh, okay. Thanks. I have read of it. Are you British?

The rhyme continues: ...

"Gunpowder, treason and plot
I see no reason why gunpowder treason
Should ever be forgot

Guy Fawkes, Guy Fawkes ... "

So it is Guy Fawkes Day, or Guy Fawkes Night, or Plot night, or Bonfire Night in Britain. It dates from 1605.

uhhh....what is tonight?????
