You could also say "Sure if I can borrow your <insert the="" name="" of="" their="" hobby="" equipment="" here="">*insert the name of their hobby equipment here*" It would be great to see the look on their face when you ask that.
Some people have no problem trying to borrow a sewing machine, especially if they've seen them at WalMart, because they're "inexpensive", not realising that they can be $1000s of dollars, but if you ask to borrow their Canon 5d Mark3 with all the lenses, I bet they choke on their gum.</insert>
