Honestly, I'm surprised that the general concensus seems to be that they keep their pants on. Get yourselves down to Browns in Shoreditch and you'll see that nothing is left to the imagination. Some of the girls are more like strippers, but some have got the pole dancing skills as well.
It's alright for a laugh on a lads night out, but it's not something you'd want to do all the time. After a couple of hours you do start to look around and think, "Has this what it's come down to? Paying money to see girls take their clothes off?". :)
