Graham Owen's flies are not to be believed, and with the paragraph below, no need to even catch-and-release:

I enjoy creating artistic and realistic flies, which are not designed primarily for fishing, just having fun trying to imitate insects and striving to make them look as alive as possible. Some of these flies have been acquired by collectors and placed on display, others used for product photo shots, and some presented as gifts. Tying flies is both challenging and fun.
