(Three runways, two intersections and a lesson in geometry.) While doing touch and goes at my home airport...

Tower: Experimental XYZ, cleared to land 17, hold short of 35.

Me (without thinking): Roger, cleared on 17, hold short of 35.

(Several seconds later.)

Voice on frequency: I want to see this!

Another voice: Me, too!

Tower: Uh, Experimental XYZ, make that hold short of 22.

Voice: Darn!
