Feather Finger is a 1966 Warner Bros. Merrie Melodies cartoon directed by Robert McKimson.
Daffy Duck is poor and begging for charity when he sees a notice that Mayor Katt is hiring gunslingers for $15 per week.
After speaking to the mayor, Daffy agrees to catch Speedy Gonzales, "the fastest mouse in all Mexico."
Next, he offers Speedy a drink of nitroglycerin, but the mouse lets it slide down the counter and explode (Daffy: "This is getting monotonous").
His next attempt involves shooting a cannon at Speedy, which also fails, as he is smashed into a canyon wall.
