I need to know: Did Bob *actually* piss his pants???

Title. Did he actually?! Or did he like, pour water on himself for the bit? I mean, I respect the commitment to the bit either way, I just really really wanna know.

EDIT: Thank you all for your responses and insight. Unfortunately, I am a dirty, filthy, poor Listener (on Spotify). I'm allowed to wear one earbud while working, which is a rare treat at jobs I've had.

CONCLUSION: Bob is definitely a pissy pants-wetter (but not actually; he used water from a water bottle)
