Name's the Same/Web Comics

In Tailsteak's comic "Band", there are two Brian Smiths. They met when one got in trouble for something the other did; they vowed never to reveal their middle names and they've been friends ever since.
He's also not the same Brian Smith as Lazarus Long's father in Robert A. Heinlein's Time Enough for Love.
One's a male human and the other's a female gorgon but they're both named Elan.
There are two very, very different "Angels" comics with characters codenamed Bubblegum: Angels 2200 and United States Angels Corps. The former is reasonably worksafe. The latter is not even worksafe in Hell.
When British rapper Skepta created a pornographic music video called All Over The House, hits on the webcomic All Over the House went up 1000%.
A briefly somewhat important supporting character in Wapsi Square is a singer-songwriter named Heather Mills. This is never Lampshaded.
An internal example among Andrew Hussie's many works: "Lil' Cal" is a name he often used for various rapper characters, but it's probably far more remembered as the name of Homestuck's Demonic Dummy.
