Laugh at the bizarre 'similar questions' that are seemingly randomly brought up when you post a question on here? Are they ever relevant? I have always found them to be so unconnected I don't understand what engine this site uses to connect previous posts to the question you are asking.
Yes - it's a bit like if you do a google search on 'Used toilet paper', and the adverts pop up on the right hand side..
'Buy used toilet paper on Ebay! fantastic low prices!' etc.
