Tips
- Inflate or stuff the belly pad just enough to look round but still allow you to sit down comfortably.
- Bring extra spirit gum or double-sided tape, as heavy fake mustaches tend to peel off when you talk or laugh.
- If wearing a bald cap is too warm, you can substitute it with a black or blue flight goggles headband worn over your head.
