From teenager in 1991 to Statler & Waldorf just 30 years later -- that's what I call rapid progress... ::)

from starting messing around with vale radios etc at an early age maybe 5 or 6yrs old,when i was about 10yrs old my folks tv went south,it was there first colour set (very expensive then circa 1974),they asked me too look at it,well it had been unplugged and turned off for about 5 mins,i went to unplug the anode cap next thing i landed about 7 feet away on the other side of the room,i have had many clouts over the years but that one i remember as being the worst!.

DavidAlfa:
Unless you have some heart disease, not really.
You won't get "stuck" like when touching mains AC, the current is just a few mA, the initial discharge will instantly trigger a nervous system reflex, before you even realise, just like when touching a hot plate.
If you ever get shocked by it, specially by the tube (Which is a capacitor itself), you will learn something, and never forget :-DD

schmitt trigger:
As others have mentioned, the real danger is with the violent reflex motion after receiving a shock.

When I was an EE student I had a part time job at a local TV shop.

One day aligning the convergence and purity of a color TV, which I had powered up while I was manipulating the back controls. For this procedure I was really focused watching the CRT image’s reflection on a mirror. I touched an HV point, don’t know exactly what.
I sprang backwards, lost my balance and hit a vacuum-tube amplifier chassis with the back of my head. Since I broke several tubes with my skull, glass shards lodged deep in the skin, which had to be painfully removed before stitching me up.

This accident left a scar which 47 years later I still have.

woofy:
Its an old thread,

but as others have said, not really lethal at all. The real danger is the reflex action in pulling your hand away and cutting yourself on the sharp chassis. I spent the first first half of my life as a TV engineer for a once national and now defunct company. Cut hands and lots of colourful metaphors is all I really got from it. The voltage in a colour tv was around 25kv but at a low current. It sparked and left a small burn point. Tv tubes make a fine high voltage capacitor, so it was essential to discharge it before changing the tube.
