Bands: The Beatles, Elvis
Foods: pie (If I ever figure out who made that overused on the Internet, he/she is gonna pay...)
TV shows: Once again, drawing a blank
Etc.: Nearly all overused jokes that don't fall into the above categories. The ones I can think of off the top of my head are "SH00P DA W00P", "I see what you did there", "That's what she said", "your mom", and almost anything that originated from Sonic the Hedgehog, Mega Man, Metal Gear, and Halo fanbases. There are some overused jokes I like though, such as "boot to the head".
