Will a man get electrocuted if he places the electrical test screwdriver on his foot?
If the man is totally isolated from any other circuit path the current through the man would be the same regardless of order.

However, the possibility of inadvertently touching something else during the process, e.g. putting a foot down, makes this a highly inadvisable experiment.

BTW you may find this cross post interesting. Wearing rubber soled shoes is highly advisable when using these testers.
