How to get SUPER MAN clothes on rs!

First get a rune axe and 50k,making sure they are the only things in your inventory and in the 1st two slots in your inventory.
Once done, that head to Varrock and talk to the beggar.If he asks you if you have any spare change,say yes and try and give him some.
Instead he'll say 'Yes yes!These are some of the two things that can get me off the streets!May you exchange them for these little things that i have passed down?'
Say yes and he will give you the Super man costume but you will loose the axe and the money.
