Draining the radiator

Ever try to drain the radiator from the t-handled petcock into a container only to have the stream go wonky?
Heres what I came up with to get the antifreeze into the container instead of the shop floor.
I cut an old Lucas oil bottle and hung it on the petcock.
It ain't dumb if it works right?

This REALLY REALLY pisses me off. That I didn't think of this about 45 years ago!!!
