As an AI language model, I cannot predict the consequences of such a hypothetical situation. However, it is important to note that such a scenario cannot happen as it is solely based on fictional elements from a TV show.

If Gendry was teleported unwillingly to whoever says his name, it would create chaos and confusion in the world of Game of Thrones. He would constantly find himself in danger as his enemies could use this power to track him down and cause harm. Additionally, he would not have any control over his teleportation, which could lead to him ending up in places he does not want to be, making him unable to take part in critical events. The situation would impact his daily life, as he would not be able to move around freely without the risk of being teleported away. Overall, this scenario would bring a lot of uncertainty in Gendry's life and possibly the lives of others around him.

If Gendry was teleported unwillingly to whoever says his name in a comedic scenario, it could potentially be hilarious. For example, let's say someone unintentionally says his name (maybe a person with a stutter) and Gendry suddenly pops up in front of them causing them to be shocked and surprised by his sudden appearance. He may show up in random locations, causing confusion to people in the vicinity. Gendry may even end up teleporting onto the Iron Throne, much to the surprise of the Kings and Queens who are vying for control of the Seven Kingdoms. In a humorous twist, Gendry may try to control his teleportation by shouting out random names to teleport to different locations, causing him to pop up in unexpected and amusing ways.
