"Hello, YouTube" in Perl, C, C++ C# and Python

This is my first video for my programming and gaming channel. In the spirit of programming, I have done "Hello, YouTube!" in Perl, C, C++, C# and Python. Please pardon the sloppy editing, I was in a rush to get a Pi-Day video (3/14) I missed the upload, but at time of recording it was pi-day. --- Skipto: Perl - https://youtu.be/q8vC2zUuRMg?t=68 C - https://youtu.be/q8vC2zUuRMg?t=176 C++ - https://youtu.be/q8vC2zUuRMg?t=265 C# - https://youtu.be/q8vC2zUuRMg?t=377 Python - https://youtu.be/q8vC2zUuRMg?t=489
