Keeping in line with the tradition of asking his celebrity guests to perform the most unusually incredible tasks, Fallon asked Radcliffe to play a game of stick balls, wearing Velcro-suits.
The rules are simple; the two participants have to throw many sticky balls at each other as possible for 45 seconds. Whoever is covered with the most balls in the end loses.
Sounds fun, doesn’t it? It was in fact the best highlight of Wednesday night’s show.
Find out who wins the game in the hilarious video above.
