VIDEO: Schalke's Leroy Sane freaks out when Franco Di Santo puts something down his shirt

Franco Di Santo is loving life at Schalke.

During the club's 5-0 demolition of second-tier side Duisburg in a German Cup match Saturday, the striker - in a jovial mood given that his team was running away with the match - took some time out while celebrating a goal to play a practical joke on teammate Leroy Sane.

The Argentine, who joined the club this summer, finds something in the grass - thought by some to be a spider - and sends Sane into a frenzy when he puts it down the teenager's shirt.

Whether is was a spider or not, it was enough to spook Sane and elicit a hilarious reaction that is a joy to watch - right up until you consider how you would react if someone pulled this stunt on you.

Not so funny anymore, huh?
