Happy Birthday Dave! It was David Letterman’s birthday on the 12th April (last Saturday) and Lyle The Intern remembers, of course. Check out the clip embedded below for what Lyle gave Dave, and there’s another clip – “Bros for life”. Jimmi Simpson (probably best known for his appearances in It’s Always Sunny In Philadelphia) is great as Lyle The Intern – his act is hilarious – I think he’s on a par with the quality of the great Johnny Dark’s polished act. Check out some of Lyle’s past appearances here.
