Jesse Tyler Ferguson and Eric Stonestreet took a walk down memory lane recently and ended up having quite the trip.
Ferguson stopped by "Conan" on Tuesday, where he opened up about the pair's awkward encounter while visiting his costar's old fraternity at Kansas State University.
"We knocked on the door at 2:30 and here are two people from television, iconic characters if you ask me, and they were so thrown off like what are you doing here," Ferguson explained. "They had just thrown this huge party where they trashed the frat house."
But that's not all the frat party fun the two had -- Ferguson and Stonestreet also decided to pop into Eric's old room at the house, unannounced.
"He just opens up a room that he used to live in and there was a man in there with his lady friend and they were under the sheets doing naughty things," Ferguson says.
"They were like hey! And she's like covering herself up with her sheet,” he laughed. “And they were like 'Oh, my God could we get a picture with you guys?' And we took photos with them.”
