You know how it is with child stars -- they grow up so fast before our eyes and before you know it ... they're being tased by hotel security.
Zachery Ty Bryan, who played Brad Taylor on "Home Improvement" -- is suing Choice Hotels International over an incident back in April 2008. Zach claims he was staying at a hotel in San Diego when he and a few friends went across the street to grab a Gatorade. When he came back just after midnight, Bryan's lawyer claims the hotel wouldn't let him upstairs, since the room wasn't in his name.
Then things went really bad ...
A hotel employee tells us Zach went nuts on the staff, a lot of alcohol was involved, and tasering the dude was the only safe bet.
Zach is suing for damages in excess of $25,000. A lawyer for the hotel had no comment.
